MCQ
To draw maximum current from a combination of cells, how should the cells be grouped
- ASeries
- BParallel
- CMixed
- ✓Depends upon the relative values of external and internal resistance
✓
Answer
Correct option: D.
Depends upon the relative values of external and internal resistance
d
(d) Maximum current will be drawn from the circuit if resultant resistance of all internal resistances is equal to the value of external resistance if the arrangements mixed. In series, $R > > nr$ and in parallel, the external resistance is negligible.
