A power supply to be constructed from voltage cells is required to supply a maximum current of 20 amperes with a terminal voltage of approximately 6 V. Several voltage cells are available, each of which has a terminal voltage of 1.5 V and each of which can supply a maximum current of 5 A. The number of cells required will be

Solution

The correct option is A 4
Given,
Total voltage $= 6 V$
Total Current $= 20 A$
Cell Voltage is $1.5 V$
Cell current is $5 A$
Therefore,
Number of cell $= \frac{T o t a l v o l t a g e}{C e l l v o l t a g e}$
Number of cell $= \frac{6}{1.5} = 4$
Correct option is A.
