oscillate Vary predictably, or rhythmically, between two extremes, usually within a set period of time. An alternating current (AC) waveform, for example, oscillates between maximum and minimum electrical values, which are positive voltage (+V) and negative voltage (–V), respectively. See also AC, voltage, and waveform. 74570c15.qxd 9/11/07 12:26 PM Page 352 |
