Q. a set $f$ ' $n$ ' identical resistors each of resistance $R$ ohm when connected in reries have a effective resistance of $x$ ohms and when connected in parallel the effective resistance of $Y$ ohms. Then the relation between $R, X$ and $Y$ is

Solution:

WKT $R_{s}=n R $
$R_{P}=R / n$
$X=n R $
$Y=R / n$
$X Y=R^{2}$
therefore $R=\sqrt{X} Y$
