Q. There are $n$ similar conductors each of resistance $R.$ The resultant resistance comes out to be $x$ when connected in parallel. If they are connected in series, the resistance comes out to be
A) $x/n^{2}$
B) $n^{2}x$
C) $x/n$
D) $nx$
Explanation
(b) In parallel, $x = \frac{R}{n}\ \ R = nx$
In series, $R + R + R\ldots n$ times $= nR = n(nx) = n^{2}x$
