Look closer at the way in which you found those two components wired up. That makes all the difference. The capacitor is in series from one side of the transformer only. The diode is not in series, it's paralleled to hot and neutral. This is not an ac to dc half wave rectifier as you thought; it's a ac to dc half wave voltage doubler.
Er, nope. You'll get a bit more than that, not including losses in components.
Wrong again. It's a crude half wave voltage doubler. Look at the way in which the diode and capacitor are wired to each other and the secondary side of the transformer. It's a voltage doubler circuit, not a half wave rectifier as you originally thought.

No, I'm not. I've provided various videos clearly showing arcs in excess of an inch in length being created from far less voltage than the 75kv you claimed was necessary.
I'm well aware of that. You should have watched a video or two before assuming I don't know anything about this subject. I assure you, I do.

I think I found a video that'll explain this better than I did. :)

Heh. That's based on a shitload of remodel work. Many (not all) homes still had various copper connections...
I'm not going to argue with you about this. I'll let another video show you, instead:

ROFL. I'm trained in medium voltage and high voltage as well. I know it doesn't take 75kv to jump an inch.
That's a shame. You'd have learned something.
Good for you. So, at what point did you confuse a half wave rectifier circuit in a microwave oven for a voltage doubler? Didn't pay close enough attention to the wiring, huh? A single diode and capacitor will make a crude voltage doubler circuit, if wired differently. Yes, it f****ng will.

It's all in HOW THE TWO COMPONENTS are connected to each other and input/output. See the schematic? Mr 'wiring circuits back in the early seventies' but confuses a voltage doubler for a half wave rectifier, simply because he didn't bother to look at how they were connected; just ASSumed it couldn't be anything more than a half wave ac to dc rectifier, since it's only using one diode and capacitor.
That's a stupid move on your part. Had you been f****ng around with that circuit, you'd have gotten a bit more than the 2kv or so 'dc' you incorrectly thought it was. It's dc, (pulsed dc), but it's not still around 2kv by then, it's much closer to 5kv.

Another video showing a considerable amount less than 77kv, but still making a nice arc. See how far he can draw it? The caps aren't magically allowing him to create 77,000 volts as you claimed was needed....And it's going further than an inch. He can actually hold it, until it melts the contacts away. [g] And that's not even using the voltage doubler circuit; just the transformer and a collection of capacitors. The transformer on it's own can make and sustain a nice arc, well in excess of the inch you claimed wasn't even possible at 2kv - which is all that particular MOT is making..You notice as he adds capacitors, the secondary side AMPS is increasing? See what that does with the arc? Yes, it's a more intense arc, sustaining, at
2kilovolts.
And that arc can f****ng kill you dead. It's NOWHERE NEAR 77,000 volts as you originally stated it would need to be. The caps are increasing the intensity (higher amperage) of the arc, but the voltage isn't increasing with it. 2kv (not even voltage doubled or converted to dc) and 5 caps are making 2kv in excess of 3amps. Not something you want to come into contact with. And, nowhere near the
77kv you claimed was required to jump open air.
Your math is flawed, sorry, but it is.

Here is where your stupidity comes in. Once an arc is established the nodes can be drawn apart and the arc will continue.
ANY idiot trainee like you would know that from simply watching the now years old video of a set of breakers opening at a substation.
To put it simply, child. It requires VOLTAGE to breach a gap.
It require continual current delivery capacity to fry things once that gap is breached.
So a 10kV ignition transformer for a kerosene heater bridges a specific gap. ONCE an arc is established, it drops to about one kV, but maintains the arc, yet ONLY provides a couple mA at that level, which means that LOAD matters. It is NOT 10kV from the moment that arc is established forward, as it CANNOT drive that virtual zero ohm load. It gets clamped down by the load.
NOW, you precious pole pig, on the other hand, can drive several hundred amps into a short load. That is a MAJOR difference. The HV line feeding it comes from a transformer capable of providing hundreds of amps AT the voltage it delivers. THat is VASTLY different than a piddly kerosene ignition transformer. And you appear unable to see that difference.
So your victim does not get fried by voltage. He gets fried by the current, because POWER distribution systems are MADE to DELIVER POWER. The voltage merely provides the initialization, as the idiot got in between two nodes and made a current path.
So where you failed is your bent brained thingking that everything has massive amperage capacity. YOU think "it takes current". You are not fully educated and lack some physics knowledge. To bridge a node gap, it takes POTENTIAL or no breach occurs. Once said POTENTIAL cause a breach, THEN the current delivery capacity of said nodes comes in to play.
That is why lightning only lasts for a very short period. Very high voltage, and very low storage (relatively)means a lot happens, but for only a very short period.
Otherwise we could capture and store and make use of lightning energy.
Real power delivery requires the ability to feed that load constantly.
You missed something in your training or it is an incomplete course.

You are a goddamned idiot, boy.
I have seen line shorts fry a person's arm completey off. And she was 25 feet from the arc event location.
I do not "think I know more than I do". I KNOW that I know more than you do, however.
You are a fresh trained wire boy punk, or someone trained longer ago, but whom never ever really got the physics right in your lacking screw driver turning head.
Otherwise, you would have never made the layman phrased statement you made about it requiring current as well as voltage to breach a gap.

Oh look. You finally got one right.
criude... yes.

Therefore NOT a "voltage doubler" as you have been claiming. It is a "half wave voltage doubler" at best.

Your videos show nothing about "it's not just the voltage".
Again, your original assertion is incorrect. Period. The ONLY thing that matters in breaching a gap is VOLTAGE.
The ONLY thing that matters when your body is passing current is that current LEVEL. That is AFTER the arc is established.
Obviously not.
When you say "it's not just the voltage it's the amperage", you cause your previous stated assertion about yourself to fall flat on its face.
And just so you know, and yes it has already been also argued here, "amperage" is not a word.
Maybe now you will get it.

More You tube BS.
Have you actually tried the circuit ? I just did to see. I only used a
6 volt transformer. A 1 UF capacitor and a diode rated for 3 amps. With a 40,000 ohm load. The meter is a Fluke, not the HF quality.
Adjusting for a 6.0 voltage AC the DC voltage did not make 8 volts. That is in line with the 1.4 times the AC voltage and diode drop. Just like a 1/2 wave rectifier .
If it was really a voltage doubler, it should have been over 10 volts DC allowing for the drop of the diode.
It still takes 2 diodes and 2 capacitors to do the voltage doubling for a 1/2 wave doubler.
You should really verify anything you see on youtube before stating it as fact.

Ralph Mowery
I will concede that you do get a doubling of pulse voltages in this particular case.
Just not a DC voltage one normally thinks of when mentioning a voltage circuit. Found this out by putting a scope across the circuit after someone else mentioned how the pulses were offset in the negative direction.

It is all the microwave magnetron cavity needs to resonate.
Probably pretty lossy with what gets used from the outlet over what gets pumped out of the magnetron cavity into the load (food).
I was wiring circuits back in the early seventies, *and* I know what the term 'continuity' means.

Too funny. First circuit diagram and description is the same one found in most MOT driven end user microwave ovens. Just like I said.
A voltage DOUBLER circuit, not a half wave rectifier as you and another poster incorrectly assumed it to be.
I rather like it myself.
My brain? Oh, you think I wrote each and every single sig it generates eh? Just how much trouble does your tendency to quickly ASSUme things (often in error) get you in on a daily basis?
The sigfile is a collection of other sig files, merged into a larger file that I've collected along the way, some going back to the fidonet days. So not sorry if you find it bothersome. If anything, it brings a smile to my face to know you don't like it. [g]
Oh, and incidently, I wouldn't let you wire a light fixture to a dog house; I'd be worried you'd f*ck it up.

Not only do you try desperately to be insulting, you also like to dance around the topic when called out.
Evidently, based on the fact you started by claiming 77kv was necessary to jump an inch of open air, and dismissed it entirely as voltage related; nothing to do with amperage, frequency, ac/dc, etc.
ALL Of that is factored into the arc. It determines whether the arc is going to be a hot or a cold one, it determines how far that arc can travel and how much punch it's got upon initialization and during the sustainment phase; if it can be sustained.
Your insults aside, I told you, more than just voltage is involved, your maths is wrong. Has always been wrong. It does not take 77kv to jump an inch of open air. You were writing horse s*it. And I repeatedly told you this.
With all due respect, I think you've ASSumed incorrectly enough in this thread. You claimed 77kv was necessary to jump an inch open air gap (it isn't). You claimed the microwave oven was using a half wave rectifier (it's not). Well, the Villard circuit predates you by a considerable margin. That's the circuit the microwave oven uses to generate 5kv of pulsed DC to power the magnetron. It was created in
1904. How did you miss it?
I'll take anything you claim to know with more than a small bottle of salt. Someone who's been into electronics for anywhere near the length of time as you've claimed should be well beyond basic stuff, and shouldn't have missed something as obvious as that; or proceeded to argue about it. Yet, you did.

Oh, you don't need youtube for this.. It's just easier with a video...

See the first circuit diagram? Look familiar to you? :) The diode is reversed in the Microwave oven, but the concept is still the same. The microwave as you learned, is using a negative dc pulse, the circuit as shown is a positive dc pulse.
It's the same circuit you and another poster not only confused for being something else, but assumed I didn't know WTF I was writing about as you both did so. Not the case. I knew what I was writing about, neither of you actually did.
Many times. I originally learned about it in the early 1980s. And i've had many refreshers on it since then. It seems to be something that every serious instructor I've had wanted to ensure we knew and understood. I've been certified at one point or another to work on a variety of HV and LV stuff, so, this circuit came up several times. it's a real cheap way of acquiring high voltage.
<G> I wouldn't waste my time, yours, or anyone elses here by writing bullshit that I couldn't support with facts, if asked and was necessary.

Great. Mr Villard would be pleased that you finally figured it out, if he were still alive today. He created it in 1904, so it's not like you and others haven't had plenty of time to familiarize yourselves with the circuit. Many others are based on it. If you're into high voltage, you've probably built one or more variations of it. You've used things that are using circuits based on it, too. CRT television sets are a good example...
That's what happens when you ASSUme things and roll with those assumptions. I appreciate your followup post though.
