What do you know mean by phase lag and phase lead?
- Ans 1: The angleθ which specifiesthe instantaneous value of the alternative voltage current,gives the phase lag or phase lead of one quantity over the other.The phase differencebetween two alternative quantity is observed at different points.The quantity which has greater phase at all points is said to be leading and the other is said to be laggingbehind.
