An equiring physics student connects a cell to a circuit and measures the current drawn from the cell to I_1 . When he joins a second identical cell is series with the first, the current becomes I_2 . When the cells are connected in parallel, the current through the circuit is I_2 . When the cells are connected are in parallel, the current through the circuit is I_3 . Show that relation between the current is 3I_3 I_2 =2I_1(I_2 + I_3).

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 ?

A cell supplies a current of 1.2 A through two resistors each of 2 Omega connected in parallel. When the resistors are connected in series, it supplies a current of 0.4 A. Calculate : e.m.f. of the cell.

If n cells each of emf xi are connected in parallel, the effective emf of the combination is :

Condensers of capacities 5F and 10F are connected in parallel in a circuit with a cell of e.m.f. 2V. The capacity of the condenser to be connected in series with parallel combination of the condensers to get 1C charge to flow in the circuit is
