Question

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. $nx$

Answer 1

Answer: (B)

$n^{2}x$

Answer 2

In parallel, $x = \frac{R}{n}$ $R = nx$

In series, R + R + R .... n times = nR = n (nx)

= n²x
