A:
- A capacitor is a passive electrical component that is capable of storing energy in an electric field. It has two terminals and is also known as a condenser or condensator.
- A capacitor in an AC circuit has a property called reactance. This is the restriction on current flow due to the impedance of the capacitor. It depends on the frequency and is given by,
Here f is the frequency of the AC and C is the capacitance.
