AC voltage
Outlet power type
AC voltage is electrical potential that periodically reverses direction, alternating between positive and negative values.
This is the form of electricity delivered to homes and businesses through power grids: The outlet provides 120 volts AC voltage.
The frequency of alternation—typically 50 or 60 cycles per second—varies by country.
Contrast with DC voltage, which flows in one constant direction.
