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