The current $i$ passed in any instrument in an A.C. circuit is $i = 2 sin ω t$ amp and potential difference applied is given by $V = 5 cos ω t$ volt. Power loss in the instrument is:

Options:

Answer:

Solution:

$i = 2 sin ω t$ $V = 5 cos ω t$ $I (max) = 2 amp, V = 5 V$ $P = VI = 5 \times 2 = 10$ watt.
