Arefe Naderlouei In the potentiometer circuit below, the moveable contact is placed at N on the bare wire XY, such that the galvanometer shows zero deflection.
The resistance of the variable resistor is now increased.
What is the effect of this increase on the potential difference across the wire XY and on the position of the moveable contact for zero deflection?
