Question

- A circuit whose resistance is R is connected
to n similar cells. If the current in the circuit
is the same whether the cells are connected
in series or in parallel, then the internal resis-
tance r of each cell is given by :
(a) r=(R/n)
(b) r=nR
(c) r=R
(d) r=(1/R)​

Answer 1

Answer:

I think r=R is the correct answer
