In the experiment of potentiometer, at balance, there is no current in the

In comparing emf's of 2 cells with the helf of potentiometer, at the balance point, the current flowing through the wire is taken from

At the moment when the potentiometer is balanced

At the moment when the potentiometer is balanced,

At the moment when the potentiometer is balanced.

In a potentiometer, balance point is obtained, when

At the instant, when potentiometer is balanced, current

The length of the potentiometer wire is 600 cm and a current of 40 mA is flowing in it. When a cell of emf 2 V and internal resistance 10Omega is balanced on this potentiometer the balance length is found to be 500 cm. The resistance of potentiometer wire will be
