Two identical cells each of emf 1.5V are connected in series. IF this combination of cells is connected to a resistance and a galvanometer in series, the current that flows through the circuit is 1A.If the cells are connected in parallel the current becomes 0.6 A, Determine the internal resistance of each cell.

A galvanometer connected with an unknown resistor and two identical cells in series each of emf 2 V shows a current of 1 A. If the cells are connected in parallel, it shows 0.8 A. Then the internal resistance of the cell is

Two identical cells connected in series send 10 A current through a 5 Omega resistor. When they connected in parallel, they send 8 A current through the same resistance, the internal resistance of each cell is

A circuit consists of a resistance R connected to n similar cells. If the current in the circuit is the same whether the cells are connected in series or in parallel, then the internal resistancer of each cell is given by

n identical cells each of emf 6 V , connected in series with an external resistor of 5Omega , carry a current of 10A . If two cells are connected wrongly in series with the same external resistor, the current flowing through the cells will be 8A. Find the value of n and r the internal resistance of each cell.

A galvanometer together with an unkonwn resistance in series is connected across two identical cells, each of emf 1.5 V. When the cells are connected inseries, the galvanometer records a current of 1 A and when the cells are connected in parallel, the current =0.6 A. What is the internal resistance of each cell ?
