A) \[\frac{1}{2}\]
B) \[\frac{1}{3}\]
C) \[\frac{1}{\sqrt{3}}\]
D) \[\frac{1}{\sqrt{2}}\]
Correct Answer: A
Solution :
We know that, \[{{i}_{wL}}={{i}_{wL}}={{i}_{rms}}\operatorname{sino}|\] \[\Rightarrow \] \[\sqrt{3}=2\sin \text{o}|\] or \[\sin \text{o}|=\frac{\sqrt{3}}{2}\] \[\Rightarrow \] \[\text{o }\!\!|\!\!\text{ =}\,\text{6}{{\text{0}}^{o}}\] So, power factor \[=\cos \text{o }\!\!|\!\!\text{ =cos6}{{\text{0}}^{o}}=\frac{1}{2}\]
