AC is generated using Alternator. DC is generated using DC generator.

AC changes its direction periodically. DC do not change its direction periodically.

AC have non zero frequency. DC have zero frequency.

We cannot store AC but we can store DC.

Transmission of AC is cheaper than DC because DC transmission required costly converting stations.

We can use AC with transformer. We can not use DC with transformer.

The parameter use in AC is Impedance. The parameter use in DC in only resistance.

Power factor of AC is between 0 and 1. But power factor of DC is always 1.
