Question

When n number identical cell of emf E and internal resistance is connected in parallel, the net emf of the system will be

• A. E
• B. nE
• C. E/n
• D. n/E

Answer 1

The correct option is A E

All Cells are parallel, therefore the voltage should be same across each other and as they are connected parallel, the resistance gets reduced .as equivalent resistance gets reduced when connected in parallel. therefore if $n\to infinite$ then $R_{Equivalent}\to 0$

Hence overall voltage =E.

and current rating gets increased of the total circuit.
