Question

Can a capacitor of suitable capacitance replace a choke coil in a ac circuit?

Open in App

Solution

We know that cpacitor offers REACTANCE. So emf lags current by 90^o. The average power consumed in capacitor is zero as cos 90 = 0. So it will decrase ac current without consuming power so it can replace choke coil in ac circuit.
