For the following diagram the galvanometer shows zero deflection then what is the value of R?

In the given circuit, the galvanometer G gives zero deflection. What is the value of resistance X ?

In a Wheatstone's bridge P=100Omega, Q=1000Omega and R = 40Omega . If the galvanometer shows zero deflection, determine the value of S.

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

Figure (a) below shows a wheat stone bridge in which P, Q, R, S are fixed resistances, G is a galvanometer and B is a battery. For this particular case the galvanometer shows zero deflection. Now, only the positions of B and G are interchanged, as shown in figure (b). The new deflection of the galvanometer - s

A magnet kept at the centre of two coils A and B is moved to and fro as shown in the diagram. The two galvanometers show deflection. State with a reason whether : x > y or x < y. [x and y are magnitudes of deflection]
