The power factor of an ac circuit having resistance R and inductance L connected in series is: |
$\frac{R}{wL}$ $\frac{R}{(R^2+w^2L^2)^{\frac{1}{2}}}$ $\frac{wL}{R}$ $\frac{R}{(R^2-w^2L^2)^{\frac{1}{2}}}$ |
$\frac{R}{(R^2+w^2L^2)^{\frac{1}{2}}}$ |
The correct answer is Option (2) → $\frac{R}{(R^2+w^2L^2)^{\frac{1}{2}}}$ |
