When null point is obtained in the potentiometer the current is drawn from

When the balance point is obtained in the potentiometer, a current is drawn from?

A potentiometer experiment is set up to compare the e.m.f.'s E_(1) and E_(2) of two cells. When the null point is obtained, the current is drawn from

When a balance point is obtained in a potentiometer for finding the internal resistance of a cell, the current through the potentiometer wire is due to

When a balance point is obtained in a potentiometer for finding the internal resistance of a cell, the current through the potentiometer wire is due to

Accuracy of a metrebridge is maximum when the null point is obtained at the midpoint of the bridge wire. This is because

Accuracy of a metrebridge is maximum when the null point is obtained at the midpoint of the bridge wire. This is because

At the instant, when potentiometer is balanced, current

Null point in the galvanometer is obtained when a cell of emf E and internal resisance r is connncted across the length of 22 cm wire of the potentiometer . Now a resistane of 10Omega is connected across the terminals of the cell (by closing the key K) and null point is obtained against the length of cm. The internal resistance r of the cell is -

At what point the null point be obtained in meterbridge experiment when the ratio of resistance in two gaps is 3:7 ?
