A voltage \( u= u_{0} \sin \omega t\) applied to a circuit drives a current \({i}={i}_{0} \sin (\omega {t}+\phi)\) in the circuit. The average power consumed in the circuit over a cycle is
- Zero
- \({i}_{0} v_{0} \cos \phi\)
- \(\frac{{i}_{0} v_{0}}{2}\)
- \(\frac{i_{0} v_{0}}{2} \cos \phi\)
Answer
(D) i_ 0 v_ 0 2
