Question

The equivalent resistance of $n$ identical resistors connected in parallel is $x$. If the resistors connected in series then the equivalent resistance would be:

• A. $nx$
• B. $n^{2}x$
• C. $x/n$
• D. $x$

Answer 1

The correct option is B $n^{2}x$

When the resisters connected in parallel

$R_{eq}=\frac{R}{n}=x$

$R=nx$

When resistors are in series

$R_{eq}=Rn=\left(nx\right)n=n^{2}x$
