the expected reading of the voltmeter will be :-
In the circuit shown, a four-wire potentiometer is made of a 400cm long wire, which extends between A and B. The resistance per unit length of the potentiometer wire is r=0.01Ω/cm. If an ideal voltmeter is connected as shown with jockey J at 50 cm from end A, the expected reading of the voltmeter will be :-
