Default hot wires

I ran out of petrol last night on a roundabout and blocked the traffic trying
to get on it. When my boyfriend came to rescue me he showed me how to "limp
it" out of the way using the starter motor. He pulled out a thick rubbery lead
from something, put the car in gear and let the power in the battery do all
the work.


Er what? I've done that without adjusting anything. You just put it in 1st and attempt to start the engine.

I was amazed, but when we got home, after watching him check the
battery with his little pocket meter, I was confused. Why didn't this powerful
battery set fire to such a small pocket meter when it had so much power in it?


Same reason why you can plug a clock radio into the same power outlet as a 3kW convector heater in your house.

I know the battery had loads of power left because I tested it by laying one
of his long screwdrivers across the lead terminals. It was so powerful that I
ended up melting one of them and damaged his screwdriver.


Try a thick spanner and watch the battery explode. Make sure you look very closely.

Before I could ask
anything he sent me inside. The screwdriver was a long and thin one,


Are we talking about his screwdriver or something else now?

but thicker than the skinny wires on his pocket meter, so why did it get so hot
and cause such a massive spark? When he came in I asked him again, but he
refused to tell me, saying I should leave electrics to the experts.


I'm surprised you know how to drive a car.

This morning, after he left for work, I went back into the garage to do an
experiment. I found some thin wire similar in thickness to the wires on his
pocket meter and connect the ends to the battery. It melted before I could
disconnect it, so what's going on here? I had to pull it off with some
cardboard in my hand because I would've had a nasty burn without it. It really
was that hot, and it looked like it was getting hotter. It even started to
melt the battery's plastic. Do some wires have something in them to stop them
getting so hot? Why are the wires going to my kettle cold? Why do boyfriends
treat their girlfriends like idiots? We're the same age (22) but he talks to
me like I'm only half that age sometimes, so that's why I'm asking here. Am I
in the right newsgroup?


Nevermind the newsgroup, you're on the wrong planet.

A Glesga burd and a Weegie guy are in a bar when the girl notices something strange about the Nikes the guy is wearing.
She says, "Here mate, ah no' tryin tae take the **** ur any'hin lik' that, but how come you've goat an "L" oan wan ae yur gutties an' an "R" oan the other wan?"
So the guy smiles, puts down his bottle of cider and replies, "Coz I'm a bit thick so Ah huv tae huv an "L" oan ma left fit an' an "R" oan ma right wan."
"Aw, fo ****'s sake," exclaims the girl. "So that's how ma thongs've goat "C&A" oan thum!"
