In physics and mathematics, the phase of a periodic function of some real variable (such as time) is an angle-like quantity representing the fraction of the cycle covered up to . It is denoted and expressed in such a scale that it varies by one full turn as the variable goes through each period (and goes through each complete cycle). It may be measured in any angular unit such as degrees or radians, thus increasing by 360° or as the variable completes a full period. WebPhase. When capacitors or inductors are involved in an AC circuit, the current and voltage do not peak at the same time. The fraction of a period difference between the peaks expressed in degrees is said to be the phase difference. The phase difference is <= 90 degrees. It is customary to use the angle by which the voltage leads the current. evans halshaw car supermarket plympton
