Explain the concept of lagging and leading phase angle by waveform. Answer : i) Leading phase angle : When two ac quantities of same frequency do not attain their respective zero or peak values simultaneously, then the quantities are said to be out-of-phase quantities. The ... Similarly, in the second diagram, the voltage is said to be lagging the current by Φ. ...
