n

cells each of emf

\varepsilon

and internal resistance

r

are connected in parallel, then the total emf and internal resistances will be

View answer and explanation

Correct option: A

\varepsilon, \frac{r}{n}

Option A is correct because when 'n' identical cells are connected in parallel, the emf remains the same, but the internal resistance is reduced by a factor of 'n'.
