What is a power capacitor?

A Power Capacitor is an electrical device that stores and discharges electric energy. It consists of one or more pairs of plates, separated by an insulating material (the dielectric), which are attached to two terminals that allow the stored energy to be discharged into a circuit when required.

How does power affect a capacitor?

Here, the capacitor’s energy increases when it’s absorbing power and decreases when it’s delivering power. John M. Santiago Jr., PhD, served in the United States Air Force (USAF) for 26 years. During that time, he held a variety of leadership positions in technical program management, acquisition development, and operation research support.

What are the specifications of a power capacitor?

The main specifications of a power capacitor are: WVDC (working DC voltage), WVAC (working AC voltage), power rating, rated current, temperature coefficient, insulation resistance, and dissipation factor. Each specification is discussed in detail in the article.

How do you find the instantaneous power of a capacitor?

Capacitors store energy for later use. The instantaneous power of a capacitor is the product of its instantaneous voltage and instantaneous current. To find the instantaneous power of the capacitor, you need the following power definition, which applies to any device: The subscript C denotes a capacitance device (surprise!).
