The instantaneous values of alternating current and voltages in a circuit are given as
\(i = \frac{1}{{\sqrt 2 }}\sin \left( {100\pi t} \right)\) amper
\(e = \frac{1}{{\sqrt 2 }}\sin \left( {100\pi t + \pi /3} \right)Volt\)
The average power in Watts consumed in the circuit is:
1
1 / 4
2
√3 / 4
3
1 / 2
4
1 / 8
