AC: it changes it's direction after fixed interval of time
DC: it flows in one direction
AC: it can be transmitted over long distances with less loss of energy
DC: more loss of energy takes place in transmission
AC: eg- generator, power supply to ur home
DC: eg- battery, cell

Diffrence-the magnitude of dc current is constant and magnitude of ac current is changes with time and direction of ac current reverses periodically.
Dc current cant be used for large scale supply of electricity for household purpose and ac current is used to run electrical heater etc.
The frequency of dc current is zero and ac current is 50 Hz
