A variable capacitor is designed to have adjustable capacitance. It typically consists of two sets of metal plates that are insulated from each other. One set of plates remains fixed, known as the stator, while the other set is movable, known as the rotor. The capacitance of the variable capacitor can be adjusted by changing the position of …

Using capacitors to regulate the voltage in electrical networks
Capacitors are made within a given tolerance. The IEEE standard allows reactive power to range between 100% and 110% when applied at rated sinusoidal voltage and frequency (at 25 C case and internal temperature) (IEEE Std. 18-2002). In practice, most units are from +0.5% to +4.0%, and a given batch is normally very uniform. ...
Yes, it is an adjustable capacitor. Each capacitor ''plate'' is usually a stack of vanes, with a gap between each vane. A vane looks like slightly less than half a disc, mounted on the central shaft. One ''plate'' stack is fixed, the other is rotated by the adjustment shaft. This moves the stacks of vanes in between each other.

Power factor correction will not affect the amount of true or real power of the circuit, whereas it will reduce the apparent power and reactive power in the circuit. It also reduces the total line current drawn by load and hence the burden of an electrical system. The main source of the low power factor is Inductive loads in the circuit, which normally operates at a very …
Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as shown in Figure 8.2.1, negative charge will ...
