The `n` rows each containing `m` cells in series are joined in parallel. Maximum current is taken from this combination across an external resistance of `3 Omega` resistance. If the total number of cells used are 24 and internal resistance of each cell is `0.5 Omega` then

`m = 8, n = 3`

`m = 6, n = 4`

`m = 12, n = 2`

`m = 2, n = 12`

The n rows each containinig m cells in series are joined parallel. Maximum current is taken from this combination across jan external resistance of 3 Omega resistance. If the total number of cells used are 24 and internal resistance of each cell is 0.5 Omega then

A cell which has an emf 1.5 V is connection series with an external resistance of 10Omega . If the potential difference across the cell is 1.25 V, then the internal resistance of the cell is ("in" Omega)

In a mixed grouping of identical cells, five rows are connected in parallel and each row contains 10 cells. This combination sends a current I through an external resistance of 20Omega. if the emf and internal resistance of each cell is 1.5 V and 1 Omega, respectively then find the value of I.

To get maximum current in a resistance of 3Omega , one can use n parallel rows of m cells each (connected in series). If the total no. of cells is 24 and the internal resistance is 0.5 ohm then

Two similar cells, whether joined in series or in parallel, have the same current through an external resistance of 2Omega . The internal resistance of each cell is :

N identical cells whether joined together in series or in parallel, give the same current, when connected to an external resistance of 'R'. The internal resistance of each cell is:-
