Eczema is a common skin problem that is also sometimes called atopic dermatitis. It usually affects babies and young children, but adults can develop it, too. This inflammatory skin condition is often believed to be an allergic reaction, but the cause is unknown.
The potential of each line of a three-phase system is displaced from the other two by 120 electrical degrees. The sequence, or order, in which the potential of each line reachâ¦es its peak value is termed the 'phase sequence' of the system.
Definition of Phase Shift. With regard to wave motion, a phase shift represents the amount a wave has shifted horizontally from the original wave. Phase shifts are typically measured in degrees where a complete cycle is 360 degrees. In the diagram below, the second wave is shifted by the specified amount from the original wave: Because the horizontal axis denotes time, a phase shift represents a shift in time from the original wave.
