In a series, L.C.R circuit an alternating emf (v) and current (i) are given by the equation v = v₀ sin (ω t), \(i = {i_0}\sin \left( {\omega t + \frac{\pi }{3}} \right)\)
The average power dissipated in the circuit over a cycle of AC is

\(\frac{{{v_0}{i_0}}}{2}\)

\(\frac{{{v_0}{i_0}}}{4}\)

\(\frac{{\sqrt 3 }}{2}{v_0}{i_0}\)

Zero
