What is AC Power?

• Alternating current describes the flow of charge that changes direction on and off. As a result, the voltage level also adjusts along with the current. AC is used to deliver power to things such as houses, office buildings, etc.

Applications of AC power:

• Home and office outlets are almost always AC. This is because generating and transporting AC across long distances is relatively easy. 

• AC is also used in the of powering electric motors. Motors convert electrical energy into mechanical energy (if the shaft on a motor is spun, a voltage is generated).
