  • question_answer In an AC circuit, the reactance is equal to the resistance. The power factor of the circuit will be

    A)  1                                

    B)  \[\frac{1}{2}\]

    C) \[\frac{1}{\sqrt{2}}\]                         

    D)  0

    Correct Answer: C

    Solution :

    \[\text{Tan}\Phi =\frac{x}{R}=1,\]power factor \[=\cos \Phi =\frac{1}{\sqrt{2}}\] Hence, the correction option is [c].
