`AB` is a wire of uniform resistance. The galvanometer `G` shows no deflection 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 metre bridge, the balancing length AB = 20 cm. The unknown resistance X is equal to

In a galvanometer, the deflection becomes one half when the galvanometer is shunted by a 20Omega 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 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
