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.
Power capacitors also contribute to quality power consumption by reducing losses from reactive power consumption. Power capacitors are also used in energy storage applications such as those found in electric vehicles (EVs) and hybrid electric vehicles (HEVs).
The power stored by an inductor in its magnetic field tries to control the current, while the power stored by a capacitors electrostatic field tries to control the voltage. The result is that capacitors "generate" reactive power and inductors "consume" reactive power.

A capacitive power supply usually has a rectifier and filter to generate a direct current from the reduced alternating voltage. Such a supply comprises a capacitor, C1 whose reactance limits the current flowing through the rectifier bridge D1.A resistor, R1, connected in series with it protects against voltage spikes during switching operations.
Complex Power It is very conceptual and essential to understand. For establishing the expression of complex power, we have to first consider a single phase network that''s voltage and current can be represented in complex form as V.ejα and I.ejβ. Where α and β are angles that voltage vector and…
Why Power is Zero (0) in Pure Inductive, Pure Capacitive or a Circuit in which Current and Voltage are 90 Out of Phase? These types of questions are asked in electrical or electronics engineering interviews.So let''s back …

MSalters answer is 80% correct. The estimate comes from the average power necessary to charge and discharge a capacitor at constant voltage, through a resistor. This is because a CPU, as well as every integrated circuit, is a big ensemble of switches, each one
