Real Dummies question about mains electricity

I don't think the Science Museum ever had a _really_ big VdG. Try the Boston Museum of Science if you want to see a _huge_ one (built by VdG himself).

The big noisy sparky thing in South Ken was a Marx generator or about

I assume the key word here is "batteries" (plural). If you put twenty or so in series it will most definitely kill you !

They did the same thing on 'Top Gear' fairly recently.

Biggest I've seen was at Daresbury. It dwarfs anything in a museum. It used to be open to the public from time to time.

Not if they are only 2 volt cells, otherwise MOD vehicles and HGV's etc. would be lethal to work on- think about it...

If you look carefully it says 12 volt batteries in the line above that I was referring to.

It was decommissioned in about 1992/3 and if I remember correctly parts of it were shipped off to Oz. The building still stands and seems to have lots of telecom masts on it now.

Not long now till they close the synchrotron there as well and ship bits of it off down south (RAL).

Cheers

Yes, it was on an entert^h^h^h^h^h^h motoring show, as I recall.

Ah, I was only about 9 at the time I experienced it.

Heck, I'm getting old.

The nuclear lab at Daresby used to have one - like a water tower but twice as high.

You could prolly achieve some serious hair styles with that

You think ?

I'm looking back 30+ years

Building site 110v is actually 50-0-50. What I find most worrying is those tiny American plugs being rated at 15A

A car battery has to store enough energy to be able to start the engine. It's also a characteristic of lead-acid batteries that they have a low internal resistance.
