To make sure I understand it right:
If I want to use a voltmeter to measure amps, connect the test leads to either end of a foot long piece of 10 gauge wire (or whatever gives 1 ohm of resistance). If the volts read 20, then that is 20 amps.
Correct?
I want to make some more exact amp measurements for my next series of experiments, an analog meter just isn't accurate enough.
