Alternating voltage (AC voltage) and alternating current (AC current) are electrical terms that describe voltage and current that change direction or polarity over time. 

AC voltage is a voltage that varies like a sine function with time. AC current is the current driven by AC voltage in a circuit. AC current is a type of electrical current where the flow of electrons switches back and forth at regular intervals. 
AC voltage and currents are usually sinusoidal and have definite relationships among the peak, average, and effective values. The number of cycles per second is defined as the frequency of an AC voltage or current. 

Here are some advantages of AC over direct current (DC):
AC is less expensive and easier to generate than DC.
AC can be transmitted across long distances without much energy loss, unlike DC.
The power loss during transmission in AC is less when compared to DC.
