Diff of AC and 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	Ac generators Aplliances in Home	DC Generators Eg:Cells, batteries
