Under what condition will the strength of current in a wire of resistance

R

be the same for connection is n series or in parallel of

n

identical cells each of the internal resistance

r

, when

View answer and explanation

Correct option: C

R = r

Option C (

R = r

) is correct because the current is the same in both series and parallel configurations only when the external resistance equals the internal resistance.
