what you mean by Alternating current ?
An electric current that first moves one direction; then the opposite direction with a regular frequency
In electricity, alternating current (AC) occurs when charge carriers in a conductor or semiconductorperiodically reverse their direction of movement. Household utility current in most countries is AC with a frequencyof 60 hertz (60 complete cycles per second), although in some countries it is 50 Hz. The radio-frequency (RF) current in antennas and transmission lines is another example of AC.
read lessAlternating current is varying magnitude with respect to time but it doesn't mean that current moving in one direction & then direction reverse. It is function of charges which is being attracted by positive ions of atoms in a conduction & again another ions attract same charge. The negative cycle basically is the time period of charges from one ions to another ions that's why it is alternating in nature
