AB is a wire of uniform resistance. The galvanometer G shows no current when the length AC = 20 cm and CB = 80 cm. The resistance R is equal to

In the given circuit, when the galvanometer G shows no deflection, the current in the 5 Omega resistance is ,

In the circuit the galvanometer G shows zero deflection. If the batteries A and B have negligible internal resistance find the value of the resitor R

For the circuit, the galvanometer G shows zero deflection. If the batteries A and B have negligible internal resistance, the value of the resistor R will be

In the circuit the galvanometer G shows zero deflection. If the betteries A and B have negligible internal resistance, the value of the resistor R will be:

A meter bridge setup is shown in the figure. If there is null deflection in galvanometer when length AC = 20 cm, then the value of resistance R is

A potentiometer wire AB is 100 cm long and has total resistance of 10Omega . If the galvanometer shows zero deflection at the position C , then find value of unknown resistance
