A resistance of \( 20 \Omega \) is connected to a source of an alternating potential \( \mathrm{V}=220 \sin (100 \pi t) \). The time
\( \mathrm{P} \)
taken by the current to change from its peak value of
W
rms value is:
(1) \( 2.5 \times 10^{-3} \mathrm{~s} \)
(2) \( 25 \times 10^{-3} \mathrm{~s} \)
(3) \( 0.25 \mathrm{~s} \)
(4) \( 0.2 \mathrm{~s} \)
