A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum

Power Capacitor Symbol. Power capacitors are used to defend different types of equipment from resonance and to develop power quality through absorbing harmonic currents, generated by induction load. These capacitors are available with higher values above 1 Farad. So these can be used in place of a chemical battery.

Capacitor Bank Types. Generally, the unit of a capacitor bank is known as a capacitor unit. The manufacturing of these units can be done similarly to 1- phase unit. These units are mainly connected in the form of a star/delta connection to make a whole three-phase capacitor bank. At present most frequently available capacitor units are 1-phase

Capacitors store energy as electrical potential. When charged, a capacitor''s energy is 1/2 Q times V, not Q times V, because charges drop through less voltage over time. The energy can also be expressed as 1/2 times capacitance times voltage squared. Remember, the voltage refers to the voltage across the capacitor, not necessarily the battery
