Alternating current — (green curve). The horizontal axis measures time; the vertical, current or voltage. In alternating current (AC, also ac) the movement of electric charge periodically reverses direction. In direct current (DC, also dc), the flow of electric charge … Wikipedia

Alternating series — In mathematics, an alternating series is an infinite series of the form:sum {n=0}^infty ( 1)^n,a n,with an ≥ 0 (or an ≤ 0) for all n . A finite sum of this kind is an alternating sum. An alternating series converges if the terms an converge to 0… … Wikipedia
Alternating factorial — In mathematics, an alternating factorial is the absolute value of the alternating sum of the first n factorials. This is the same as their sum, with the odd indexed factorials multiplied by −1 if n is even, and the even indexed factorials… … Wikipedia
Alternating series test — The alternating series test is a method used to prove that infinite series of terms converge. It was discovered by Gottfried Leibniz and is sometimes known as Leibniz s test or Leibniz criterion.A series of the form:sum {n=1}^infty a n(… … Wikipedia
Form factor (electronics) — In electronics, the form factor of an alternating current waveform (signal) is the ratio of the RMS (Root Mean Square) value to the average value (mathematical mean of absolute values of all points on the waveform). In case of a sinusoidal wave,… … Wikipedia
