When n cells are joined in parallel combination as shown, the strength of the current `i` is given by

When is a parallel combination used?

In parallel combination of n cells, we obtain

In parallel combination of n cells, we obtain

When cells are connected in parallel, what will be the effect on (i) current capacity (ii)e.m.f. of the cells

When 10 cells in series are connected to the ends of a resistance of 59 Omega , the current is found to be 0.25 A, but when the same cells after being connected in parallel are joined to the ends of a 0.05 Omega , the current is 25 A. Calculate the internal resistance and emf of each cell.

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).

Five cells, each of emf E, are joined in parallel. The total emf of the combination is
