The terminal voltage is `(E)/(2)` when a c urrent of 2A is flowing through `2Omega` resistance, then the internal resistance of cell is:-

The terminal voltage is (E)/(2) when a current of 2A is flowing through 2Omega resistance, then the internal resistance of cell is:-

A cell of emf 2.2V sends a current of 0.2A through a resistance of 10 Omega . The internal resistance of the cell is ______

The variation of terminal potential difference (V) with current flowing through a cell is as shown The emf and internal resistance of the cell are

The circuit diagram in Fig. shows three resistors 2 Omega , 4 Omega and R Omega connected to a battery of e.m.f. 2 V and internal resistance 3 Omega . If current of 0.25 A flows through the circuit, find : the p.d. across the internal resistance of the cell,

When a resistance of 12 Omega is conencted with a cell of emf 1.5 V,0.1 A current flows through the resistance internal resistance of the cell is

Calculate the current flows through resistance 2Omega .
