The e.m.f of a cell is 1.5 V. On conneting a `14Omega` resistance across the cel, the terminal potential diference falls to 1.4 V. Calcualte the internal resitsnce of thecell.

A cell of e.m.f E is connected across a resistance r. The potential differene between the terminals of the cell is found to be V. The internal resistance fo the cell must be

Two poles of a cell of em.f 1.5 V are connected to the ends of a 10Omega coil. If current in the circuit in the cirucit is 0.1 A, calculate the interal resistance of the coil.

Four identical cells each of emf 2V, are joined in parallel providing supply of current to external circuit consisting of two 5 Omega resistors joined in parallel. The terminal voltage of the cells ae read by an ideal voltmeter is 1.6V. Calculate the internal resistance of each cell.

Four identical cells each of emf 2V, are joined in parallel providing supply of current to external circuit consisting of two 15 Omega resistors joined in parallel. The terminal voltage of the cells ae read by an ideal voltmeter is 1.6V. Calculate the internal resistance of each cell.

A cell of emf 2 V and internal resistance 0.1Omega is connected to 3.9Omega external resistance. What will be the potential difference across the terminals of the cell?

A current of 2.0 A passes through a cell of emf 1.5 V having internal resistance of 0.15 Omega . The potential difference (measured in volt) across both the terminals of the cell is

What do you mean by internal resiatnce, e.m.f. (electromotive force) and terminal potential difference of a cell?

The e.m.f of Daniel cell is 1.09 V and internal resistance is 2Omega . If the terminals of the cell are joined by a wire of resistance of 18Omega find the potential difference recorded by a higher resistance voltmeter also connected to the terminals of the cell.
