The e.m.f. of a primary cell is 2V, when it is shorted then it gives a current of 4A. Calculate internal resistance of primary cell.

Choose correct alternative. The emf of a primary cell is 2 volt. When it is shorted then it gives a current of 4A. Its internal resistance will be

The electromotive force of a primary cell is 2 volts. When it is short- circuited is gives a current of 4 amperes. It internal resistance in ohms is

Internal resistance of primary cell depends on :–

A cell has an emf of 1.5V. When short circuited, it gives a current of 3A. The internal resistance of the cell is

A primary cell has an e.m.f, of 1.5 V, when short circuited it gives a current of 3A, then the internal resistance of the cell is

A primary cell has an e.m.f. 1.5 volt. When short circuited, it gives a current of 3 ampere. The internal resistance of the cell is
