The role of coupling capacitors is to prevent the incoming AC signal from interfering with the bias voltage applied to the base of a transistor. In such applications, the signal is driven to the base of a transistor through a serially connected coupling capacitor.

In power supply units, capacitors play a vital role in smoothing out the voltage. The power supply unit of an electronic device converts the incoming AC voltage into DC voltage. However, this DC voltage can still contain small fluctuations or "ripples." Capacitors help to smooth out these ripples and provide a clean DC voltage to the device.
Whenever an inductive load is connected to the transmission line, power-factor lags because of lagging load current. To compensate, a shunt capacitor is connected which draws current leading the source voltage.

Distribution capacitors can reduce system line losses, as long as the system power factor is not forced into a leading mode. Line losses at 80 percent leading power factor are just as detrimental as line losses at 80 percent lagging power factor.
In order to understand the usage of different types of capacitors in transmission lines we must first look in different way first the effect of power factor on the power system. Because the subject is related to the power factor correction.
Capacitors offer a means of improving system power factor and helping to correct the above conditions by reducing the reactive kilovar load carried by the utility system. For optimum performance and avoidance of these undesirable conditions, prudent utility planners attempt to maintain as high a power factor as economically practical.
Shunt capacitors raise the load pf which greatly increases the power transmitted over the line as it is not required to carry the reactive power. There is a limit to which transmitted power can be increased by shunt compensation as it would require very large size capacitor bank, which would be impractical.
As power distribution system load grows, the system power factor usually declines. Load growth and a decrease in power factor leads to Reduced system capacity. Capacitors offer a means of improving system power factor and helping to correct the above conditions by reducing the reactive kilovar load carried by the utility system.
