A resistance of \( 20 \mathrm{ohms} \) is connected to a source of an alternating potential \( V=220 \sin (100 \pi i) \). The time taken by the current to change from its peak value to r.m.s. value is
(A) \( 0.2 \mathrm{sec} \)
(B) \( 25 \times 10^{-3} \mathrm{sec} \)
(C) \( 2.5 \times 10^{-3} \mathrm{sec} \)
(D) \( 0.25 \mathrm{sec} \)
