A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser), or as a variable reactance, e.g. for impedance matching in antenna tuners.

Power Factor Correction: Reactive Power Compensation Methods

Discharge resistors are also used for each capacitor to discharge it after being disconnected from the supply in a relatively short time interval. To calculate the maximum discharge resistance, a ratio between the maximum discharge time approved by IEC60831 and a logarithmic capacitor charging must be applied.

Basic Knowledge of Capacitors (1)

In short, capacitors are components capable of storing electricity and releasing the stored electricity when necessary. They store a smaller amount of electricity (charge) than batteries and therefore can supply current for only a short …

Capacitors

What makes capacitors special is their ability to store energy; they''re like a fully charged electric battery. Caps, as we usually refer to them, have all sorts of critical applications in circuits. Common applications include local energy storage, voltage spike suppression, …

Variable Capacitor : Construction, Types and Their Applications

Once the capacitor is charged through a voltage source, then one plate of the capacitor will be charged positively whereas the second plate will negatively be charged. Basically it is like a battery but whenever the plates of the capacitor are touched, the electrical energy which is stored will be dissipated immediately, whereas, in a battery, the energy will be …
