Varactor Diode Operation
A varactor is a diode that always operates in reverse bias and is doped to maximize the inherent capacitance of the depletion region. The depletion region acts as a capacitor dielectric because of its nonconductive characteristic. The p and n regions are conductive and act as the capacitor plates, as illustrated in Figure.
Capacitor banks in power system (part 1)
If V = 1 Volt than C = Q, thus capacitance is defined as the amount of electric charge in coulomb required to raise its potential by one volt.. If V = 1 Volt than C = Q, and Q = 1 Coulomb than C = 1 Farad thus one Farad is capacitance of a capacitor which stores a charge of one coulomb when a voltage of one volt is applied across its terminal.

Capacitor Bank Testing: Importance and Procedures Explained
The power factor correction of capacitor banks changes due to moisture, temperature, time, and harmonics. To perform their best, the installed capacitor banks must be tested regularly and maintained to the highest quality. Although capacitor banks of the finest qualities function quite well, their operation can weaken with time.

Fundamentals | Capacitor Guide
What is a Capacitor? A capacitor is a two-terminal passive electrical component that can store electrical energy in an electric field.This effect of a capacitor is known as capacitance. Whilst some capacitance may exists between any two electrical conductors in a circuit, capacitors are components designed to add capacitance to a circuit.
