A choke coil has a self-inductance of $0.5\text{ H}$ and a resistance of $50\ \Omega$. It is connected to a $220\text{ V}$, $50\text{ Hz}$ a.c. supply.
(a)[1.6666666666666667]
Calculate rms value of the current flowing through the coil.
(b)[1.6666666666666667]
What is the phase difference between the supply voltage and the current?
(c)[1.6666666666666667]
What is the power factor for this circuit?
