Combination of Resistors

$n$ equal resistors are first connected in series and then connected in parallel. What is the ratio of the maximum to the minimum resistance?

Show answer and solution

Answer: (c)

Series: $R_{max} = nR$ . Parallel: $R_{min} = \dfrac{R}{n}$ .
$\dfrac{R_{max}}{R_{min}} = \dfrac{nR}{R/n} = n^2$
So the answer is (c) $n^2$ .
