To get the maximum current from a parallel combination of `n` identical cells each of internal resistance `r` in an external resistance `R`, when

Under what condition will the current in a wire be the same when connected in series and in parallel on n identical cells each having internal resistance r and external resistance R?

Under what condition will the current in a wire be the same when connected in series and in parallel on n identical cells each having internal resistance r and external resistance R?

A resistor R is conneted to a parallel combination of two identical batteries each with emf E and an internal resistance r. The potential drop across the resistance R is.

To draw the maximum current from a combination of cells, condition is, external load 'R’ should be ( R_B is the internal resistance of the combination)

An total resistance R is connected to a cell of internal resistance r the maximum current flows in the external resistance, when

Statement - (A) : Series combination of cells is preferred when external resistance is large compared to internal resistance of cell. Statement - (B) : Parallel combination of cells is preferred when external resistance is small compared to the internal resistance of each cell.

A : When two cells of equal EMF and equal internal resistances are connected is parallel with positive plate of the other than , the net EMF , of the combination will be equal to the EMF of each cell. R : Effective internal resistance of the parallel combination of two identical cells will be half of the internal resistance of each cell.
