Two ammeters in parallel

Sounds risky!

Bill

It is in an non-conducting box. It works perfectly.

Jim

But potentially good for lighting cigarettes!

That reminds me.... When I was doing work experience with the electricity boards in the very late 1980's, all their works vehicles all had signs on the dashboard saying

WARNING THIS VEHICLE IS POSITIVE EARTH

and negative earth became commonplace in the 1970's.....

I enquired around other vans for the water and gas companies then and they all had the same warning sticker

Does anyone know why?

I'd forget and connect up something with exposed metal parts.

Bill

But to be a problem the exposed metal parts have to make a short circuit. Inside the car there is only the (painted) seat frame or the door handles that your "something" might short against, because the seats are upholstered and the floor is carpeted and the parcel shelf is hardboard. Also the wire to the new cigarette lighter socket is protected by its own in-line fuse, so a short would blow it.

Jim

Don't worry, I'd f*ck it up.

Bill

If running appliance loads off the lighter socket, you might want to know that.

OK, I think I see the picture noe. I was disregarding leads as zero effect. But at very low resistivity in the shunts, I guess the leads can be a big part?

If this is the case. I get it :-)

I won't be offering you a lift then :-)

Jim

I think today's education, in a few fields, is based on software output, or, pre programmed hardware where the 'light says it's right'. Maybe?

Try convincing the youth, indeed people, of today they need to learn the long route to anything because one day they may be in a situation without a device that tells them what they need to know.

Phones today are closer and closer to 'Star Trek' tech. And, in the future, the handiest place to keep the hardware will be in the skull.

Warehouse operatives wear ear pieces and talk into a mic and get constant feedback where others have eye pieces that direct attention to a parcel and then guide to the spot it is to be placed. Amusingly, if a particular parcel is wanted, the graphic will show where it is in a block of parcels and tell you which other parcels it is easier to move to access it. Constantly scanning, the new parcel arrangement is remembered.

In the Audio workplace, talking to a workmate was frowned upon and the 'orange jackets', some who would stand with folded arms and watch you work all day would even have the balls to come and ask what was so important it had to be talked about? Disgusting, morbid places. But, at

In the 90's while re-slating a roof, the young lad working along side me asked, 'what's it like nailing your old school books to a roof'?

Or a block of cheese that can be called cheese as long as there is at least 6% real cheese within.

In the 60's I asked granddad why he has a wired switch from his tv to the armchair. Because I don't want to listen to those adverts. And, he told me why.

He also explained and told me to listen out for the 'hooks' that are used before an advert, or, at the end of an episode that is designed to draw you back. Some were so poor that the whole program would lose it's flavour. It took less than 2 minutes for the, highly acclaimed, 'Game of Thrones' thing. And, oddly enough, because of the well made up tit popping actresses.

Oh, and just the one, enjoyable, opening episode of 'Lost'. Years later when I hear people moaning about the 'ending', I had a satisfying feeling and 'sent' my good thoughts to granddad.

Honestly, there are more truths in the The Simpsons.

LOL. Excellent picture :-)

You really have demonstrated your astonishingly poor comprehension skills again. Go look at the thread again - the *vast* majority of the posters (i.e. all but a couple) were right on the money form the start, or at least quickly understood and accepted corrections.

Yes there is thread drift (usenet, what do you expect?), yes noise from TNP barking Kirchhoff at everyone like an over enthusiastic puppy, and a bit of misunderstanding about whether Bill's meters were a matched pair or not, but when it came down to it, the majority of posters answered Bill's question correctly.

Now does that mean I believe "this thread does demonstrate the group's understanding of electronic basics"? - no that is another comprehension fart on your part. While there are many posters here with excellent electronics and engineering backgrounds, that is no reason to assume its necessarily everyone's field of expertise or interest.

My first tv had a remote control. Wired of course. It had something like volume & line hold on it.

Let's get a few basic facts right.

1. The original question is very basic stuff.
2. Some contributors know the answer, some did not.
3. Too many confidently advanced bogus ideas about very basic aspects of electricity

I therefore conclude that this is one more example of this group being confused on basic electrical matters.

Then there's thermodynamic matters. IIRC your armchair expert opinions included the notion that evaporative cooling doesn't work in the uk. I've enough experience of it to know it does, though it's not the same as refrigeration a/c. Unlike you I also know how it works.

NT

Best not.

Bill

Too many people who knew the answers were correct and deliberately questioned the validity of those answers in order to wind up some other contributor.

No-one questioned the general effectiveness of evaporative cooling in the UK only that it was not effective in the UK with a crude swamp cooler - a wet towel draped in front of a fan running inside a room, or with a similar high priced snake oil product with dodgy advertising.
