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?
1) You need to learn more about electricity before playing with
powerful car batteries.
2) Your boyfriend might not be treating you like a girl, he may be
treating you like someone who has no electrical training.
3) He may not be teaching you because,
He may not be a good teacher. Just because you know
something, doesn't mean you are good at explaining it.
or
He may not know enough to explain it.
The reason the meter doesn't melt has nothing to do with the wires.
It has everything to do with the meter that they are connected to.
The meter (in VOLT mode) has a high resistance.
The resistance will RESIST the flow of electricity.
This is done so that the meter will not "drag down" the voltage it is
measuring.
This is because the meter is connected ACROSS, or PARALLEL with the
circuit.
Be careful though.
If you put the meter in AMP mode, the meter then has a low resistance.
This will cause a LARGE amount of current to flow, just as if it were
only wires connected.
This is because the meter in AMP mode is connected IN LINE, or in
SERIES with the circuit. If the meter were resisting flow, it would
affect the circuit.
Done that before. I have a crappy meter with seperate sockets for amps and volts. I have often switched the dial to volts and left the leads in the amps socket. New leads please!
