For an \( \mathrm{AC} \) circuit the potential difference and current are given by \( V=10 \sqrt{2} \sin \omega t \) (in V) and
\( \mathrm{P} \) \( I=2 \sqrt{2} \cos \omega t \) (in A) respectively. The power

W dissipated in the instrument is
(1) \( 20 \mathrm{~W} \)
(2) \( 40 \mathrm{~W} \)
(3) \( 40 \sqrt{2} \mathrm{~W} \)
(4) Zero
