A) \[\frac{\pi }{3}\]
B) \[\frac{\pi }{2}\]
C) \[\frac{\pi }{4}\]
D) \[\frac{\pi }{6}\]
Correct Answer: A
Solution :
[a] It is L ? R Circuit \[{{X}_{L}}=\sqrt{30}R\] \[\tan \phi =\frac{{{X}_{L}}}{R}\frac{\sqrt{3}R}{R}\] \[\phi =\frac{\pi }{3}\,or\,60{}^\circ \]You need to login to perform this action.
