AC power
Outlet electrical supply
AC power is electrical power delivered as alternating current—the type that flows from wall outlets in homes and businesses.
The current reverses direction many times per second (60 Hz in North America, 50 Hz in most other regions).
AC power dominates electrical grids because it transmits efficiently over long distances.
Contrasts with DC power from batteries.
