An extended interruption of AC power is called a(n) ___.

Explanation:
An extended interruption of AC power is outage. When power is completely unavailable for a period, residential and industrial loads lose supply and equipment may trip or reset. This differs from a voltage sag or swell, which are short-term deviations in voltage (sag is a temporary dip below nominal, swell is a temporary rise above nominal). Under-voltage refers to voltage staying low but not necessarily zero. The defining feature of an outage is the absence of power for a noticeable duration.
