I don't understand several things in the potentiometric voltmeter:
1- if the AVS is providing 0V while the main voltage source is providing > 0v
would the null detector move? would current pass through the AVS?
2-how does providing equal voltage stops current from flowing through the detector?
I appreciate your help.
