What are the phase angles between the two sine waves in parts (a) and (b) of Figure 11-21?
Question 11.8: What are the phase angles between the two sine waves in part...
In Figure 11-21(a)the zero crossing of sine wave A is at 0°. and the corresponding zero crossing of sine wave B is at 45°. There is a 45° phase angle between the two waveforms with sine wave B lagging sine wave A.
In Figure 11-21(b) the zero crossing of sine wave B is at —30°, and the corresponding zero crossing of sine wave A is at 0°. There is a 30° phase angle between the two waveforms with sine wave B leading sine wave A.
