A) \[\pi /3\]
B) \[\pi /2\]
C) \[\pi /4\]
D) \[\pi /6\]
Correct Answer: A
Solution :
From the condition of the question the reactance of the coil is \[\sqrt{3}\]times of resistance, so \[Z=\sqrt{3}R\] \[\text{o }\!\!|\!\!\text{ =}\,\text{ta}{{\text{n}}^{-1}}\frac{Z}{R}={{\tan }^{-1}}3\] Therefore, \[\text{o }\!\!|\!\!\text{ =}\frac{\pi }{3}\]You need to login to perform this action.
