The power fac...

Question

The power factor of an a.c. circuit is 0.5. What will be the phase difference between voltage and current in the circuit?

Open in App

Solution

Power factor = $c o s ϕ = 0.5$
$\Rightarrow$ $ϕ = 60^{o}$
Hence, the phase difference between voltage and current in the circuit is $\frac{π}{3}$
