Alternating Current vs Direct Current


1.Alternating Current

Alternating current describes the flow of charge that changes direction periodically are called of Alternating current.

Fig Alternating Current.


2.Direct Current

DC is defined as the "unidirectional" flow of current; current only flows in one direction. Voltage and current can vary over time so long as the direction of flow does not change.

VOLTAGE: - An electromotive force or potential difference expressed in volts. its Can                                Say that Any two terminals Potential Difference are called of Voltage.its                                   A Donate for ( V )

CURRENT: - Any Circuits flow of Electron are called of Current. Its A donate for ( A )


POWER FACTOR: - Voltage and current Angle are called of Power Factor.                                                         Its A Donate for ( PF ) .its A value of 0.999 or 1
