Alternating Current
What is it?
Give an example of how you use AC power.
Alternating Current (AC) is an electric current that periodically reverses direction. It is the most common form of electricity used in homes and businesses.
An example of how you use AC power in everyday life is by plugging in an electronic device such as a laptop, phone charger, or television into an electrical outlet. The AC power from the outlet is converted by the device into the appropriate voltage needed to operate.
