Difference between Alternting Current(AC) and Direct current(DC):
SI.No.
Alternating current
Direct current
1
Represented by AC
Represented by DC
2
Changes the direction of current alternatively.
Doesn't chnage the direction of current.
3
Electrons direction is in reverse path.
Electrons direction is in same path.
4
Direction of current varies with time.
One time in same direction and other in opposite direction.
Direction of current is constant.
5
Used for transmission.
(AC can be incresed or reduced depending upon the necessity. Hence it is used for transmission )
Not generally used.
(Here it is difficult to increase or decrease the voltage.)
6
Depicted in Sine waves , square waves,triangular and variable waves.
Pure and pulsating.
7
