Re: Measure 100 amps with 10 amp meter ?
There's an easier way to do it, just find a shunt resistor with a known (small) value of resistance, say 0.1 ohms. Then when you have current flowing, you measure the voltage across the shunt, with the meter in the volts position (not in the amps position).
E = Voltage
I = current
R = resistance
E=IR
R=E/I
I=E/R
So, to find current, if you read 10V on the voltmeter (example), the current is 100A (if the shunt is 0.1 ohms).
