frequency and phase angle relationship
{"Image DocumentName": "15-9: Phase Angle", "Image ImageDescription": "Fig : Two sine-wave voltages 90\u00b0 out of phase. (a) Wave B leads wave A by 90\u00b0. (b) Corresponding phasors VB and VA for the two sine-wave voltages with phase angle \u0398 = 90\u00b0. The right angle shows quadrature phase. Copyright \u00a9 The McGraw-Hill Companies, Inc.
