This article is about the device. For the physical phenomenon, see Capacitance. For an overview of types, see Capacitor types. "Capacitive" redirects here. For the term used when referring to touchscreens, see Capacitive sensing.

A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals.

The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit. The capacitor was originally known as a condenser or condensator. This name and its cognates are still widely used in many languages, but rarely in English, one notable exception being condenser microphones, also called capacitor microphones.

### Example Questions:

1. Capacitance is directly proportional to plate area and plate separation.
2. A 10 μF, 20 μF, 22 μF, and 100 μF capacitor are in parallel. The total capacitance is
3. Voltage leads current by 90° in a capacitor.
4. A capacitor of 2,000 pF is greater than
5. The true power in a capacitor is zero.
6. A 12 kHz voltage is applied to a 0.33 μF capacitor, and 200 mA of rms current is measured. What is the value of the voltage?
7. The ohm is the unit of capacitance.
8. When the plate area of a capacitor increases,
9. When the voltage across a capacitor is tripled, the stored charge
10. A 0.47 μF capacitor is across a 2 kHz sine wave signal source. The capacitive reactance is
