A) \[\frac{\pi }{6}\]
B) \[\frac{\pi }{3}\]
C) \[\frac{\pi }{4}\]
D) \[\frac{\pi }{2}\]
Correct Answer: B
Solution :
\[P=\frac{1}{2}{{V}_{o}}{{i}_{o}}\cos \varphi \Rightarrow P={{P}_{Peak}}.\cos \varphi \] \[\Rightarrow \frac{1}{2}({{P}_{peak}})={{P}_{peak}}\cos \varphi \Rightarrow \cos \varphi =\frac{1}{2}\Rightarrow \varphi =\frac{\pi }{3}\]You need to login to perform this action.
