A circuit element X when connected to an a.c. supply of peak voltage $\displaystyle 100$ V gives a peak current of $\displaystyle 5$ A which is in phase with the voltage. A second element Y when connected to the same a.c. supply also gives the same value of peak current which lags behind the voltage by $\displaystyle \frac{\pi}{2}$. If X and Y are connected in series to the same supply, what will be the rms value of the current in ampere?
Official answer
(4)
$\displaystyle \frac{5}{2}$
