Some uses of capacitors are energy storage, power conditioning, motor starters, suppression and coupling, signal processing, sensing, and supplying pulsed power. Capacitors have many uses in electrical and electronic systems.Know More
A capacitor is used for storing energy by connecting it to its charging circuit. When disconnected from its charging circuit, it then dissipates the stored energy. A capacitor can, therefore, be used as a temporary battery. Capacitors are mostly used to maintain power supply when electronic devices are being charged. In motor vehicle audio systems, large capacitors store energy for the amplifiers to use.
Capacitor banks, which are low-inductance, high-voltage capacitors, are used for supplying huge pulses of current to pulsed power applications, such as Marx generators, particle accelerators, fusion research, electromagnetic forming and pulsed lasers. Large capacitor banks, commonly known as reservoirs, are mainly used as energy sources for slapper detonators or exploding bridgewire detonators in nuclear weapons.
Reservoir capacitors are used to smooth the output of half- or full-wave rectifiers in power supplies. They are also used for power factor correction in electric power distribution.
Capacitors are often used to separate the DC and AC components of signals because they can pass AC signals and block DC signals. This process is known as capacitive, or AC, coupling. A decoupling capacitor can also be used for decoupling one part of a circuit from another.Learn more in Electricity

Megavolt amperes (MVA) power is a unit used for measuring apparent power. The apparent power refers to the total current and voltage in an electrical circuit. The term is preferred in descriptions of total electrical power in installations, and it captures both true and reactive power in an electrical circuit. It is the common rating used in major electrical installations, such as transformers and generators.Full Answer >
Wind turbines turn the kinetic energy of the wind into mechanical energy and then electricity through the use of a shaft and a gearbox that power an internal generator. Sensors in the wind turbine allow it to turn and adjust its angle for optimum wind capture. Electricity from the turbine generator goes to a substation, where it is converted to a high voltage capable of transportation through power lines.Full Answer >
