Energy that is superimposed on an AC voltage waveform is a(n) ___.

Explanation:
Energy that is superimposed on an AC voltage waveform is a transient. Transients are short-duration disturbances that ride on top of the normal sine wave, appearing as spikes or pulses in voltage or current and then quickly dying out. They are non-periodic and brief, unlike harmonics which are steady, ongoing frequency components at multiples of the fundamental. Swells are temporary increases in voltage but are more gradual and longer in duration, and outages are a loss of power rather than energy added to the waveform.
