Combination of Resistors

Resistance n, each of r ohm, when connected in parallel give an equivalent resistance of R ohm. If these resistances were connected in series, the combination would have a resistance in ohms, equal to

Show answer and solution

Answer: (a)

Parallel: $R = r/n \Rightarrow r = nR$ .
Series: $R_s = nr = n^2R$ . The answer is (a).
