To draw maximum current from a combination of cells , how should the cells be grouped ?

A

Parallel

B

Series

C

Mixed grouped

D

Depends upon the relative values of internal and external resistances

Text Solution

Verified by Experts

The correct Answer is:
D
To draw maximum current from a combination of cells, external resistance `R = ( nr)/(m),` where n, m&r represents number of row, number of columns and internal resistance respectively. Therefore, grouping of cells depends upon the relative values of internal and external resistance.
