Two identical cells whether joined in series or parallel

Asked by admin @ 20/08/2021 in Physics viewed by 286 People

Two identical cells whether joined in series or in parallel give the same current when connected to an external resistance of 1 ohm. Find internal resistance of each cell.

Answered by admin @ 20/08/2021

Answer:

Explanation:

in series combination I=nE/nR+r

in parallel combination

I=nE÷nr+R

according to question....I series=I parallel

so..nE÷nR+r=nE÷nr+R

so.nR+r=nr+R

so r=R=2

thank u
