Answer:
AC stands for alternating current while DC stands for Direct current.
There is a constant and steady flow of electric current in one direction in DC current
While in AC current direction changes periodically due to change in Voltage periodically.
In india we use 50Hz AC current which means current changes it's direction 50 times in a second.
