Alternating current
What is alternating current?
Alternating current (AC) is a type of electrical current that reverses direction regularly, similar to the voltage. This means that when the voltage goes from positive to negative, the alternating current does the same. This is in contrast to direct current (DC), where the current flows in the same direction all the time.
Alternating current is the dominant form of power in most power grids worldwide. This is because alternating current can transmit more energy than direct current and can be transported efficiently over long distances. Therefore, when you plug something into the outlet at home, you are using alternating current.
