Based on this definition, the drain efficiency cannot exceed 25 % for a class A amplifier that is supplied drain bias current through resistors ( because RF signal has its zero level at about 50 % of the input DC ).

While the voltage level is above the DC rail current is supplied by the inductor.

The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.

Direct current ( DC ) is the unidirectional flow of electric charge.

In direct current ( DC, also dc ), the flow of electric charge is only in one direction.

In engineering or household applications, current is often described as being either direct current ( DC ) or alternating current ( AC ).

Electrical networks that consist only of sources ( voltage or current ), linear lumped elements ( resistors, capacitors, inductors ), and linear distributed elements ( transmission lines ) can be analyzed by algebraic and transform methods to determine DC response, AC response, and transient response.

Ideal Independent Source maintains same voltage or current regardless of the other elements present in the circuit. Its value is either constant ( DC ) or sinusoidal ( AC ).

Oscillators convert direct current ( DC ) from a power supply to an alternating current signal.

Using inputs such as input voltage, output voltage, output current, frequency, ambient temperature, and inductance these calculators can predict the losses of the inductors core and AC / DC based on the operating condition of the circuit being used.

Another method to control the inductance without any moving parts requires an additional DC current bias winding which controls the permeability of an easily saturable core material.

Some proprietary applications, such as phantom-powered footswitch controllers, use the spare pins for direct current ( DC ) power transmission.

Model railway engines are generally operated by low voltage direct current ( DC ) electricity supplied via the tracks, but there are exceptions, such as Märklin and Lionel Corporation, which use alternating current ( AC ).

The power conditioning system uses an inverter / rectifier to transform alternating current ( AC ) power to direct current or convert DC back to AC power.

It was on September 4, 1882, that Edison switched on his Pearl Street generating station's electrical power distribution system, which provided 110 volts direct current ( DC ) to 59 customers in lower Manhattan.
