A DC circuit has two wires through which the current in the circuit flows from a source of electricity through a load and back to the source.

 

A single-phase AC circuit also has two wires connected to the source of electricity. However, unlike the DC circuit in which the direction of the electric current does not change, the direction of the current changes many times per second in the AC circuit. The 220 volt electricity supplied to our homes is single phase AC electricity and has two wires - an "active" and a "neutral".
