A circuit element \( X \) when connected to an a.c.
P
supply of peak voltage \( 100 \mathrm{~V} \) gives a peak current
W
of \( 5 \mathrm{~A} \) 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 \( \frac{\pi}{2} \). If \( X \) and \( Y \) are connected in series to the same supply, what will be the rms value of the current in ampere?
(1) \( \frac{10}{\sqrt{2}} \)
(2) \( \frac{5}{\sqrt{2}} \)
(3) \( 5 \sqrt{2} \)
(4) \( \frac{5}{2} \)
