6 Frequently Asked Questions about “Why capacitors are only used for power supply”
What is the role of a capacitor in a power supply?
As one of the passive components of the capacitor, its role is nothing more than the following: 1. When a capacitor is used in power supply circuits, its major function is to carry out the role of bypass, decoupling, filtering and energy storage. Filtering is an important part of the role of capacitors. It is used in almost all power circuits.
What is the function of a capacitor?

When a capacitor is used in power supply circuits, its major function is to carry out the role of bypass, decoupling, filtering and energy storage.
Why are capacitors used in AC power distribution networks?
The capacitors store energy and release it every cycle on an AC power distribution network to compensate for the fact that highly inductive loads such as electric motors draw a current which 'lags' behind the applied voltage.
Why is a capacitor connected in series with a load?
Capacitors are used in transformer less power supplies. In such circuits, the capacitor is connected in series with the load because we know that the capacitor and inductor in pure form does not consume power. They just take power in one cycle and deliver it back in the other cycle to the load.
What does a capacitor do in a chopper circuit?
Capacitors are also used to filter out the ripple when rectifying AC power to DC (eg: in the input stage of a variable-speed drive or inverter circuit). Also, capacitors are used to 'amplify' DC power supplies (eg: to convert a 5VDC power supply to output 9VDC). These are called 'chopper' circuits. Chopper circuits?
