Two waves having same frequency have opposite phase when the phase angle between them is
Two waves having same frequency have opposite phase when the phase angle between them is:
- 0°
- 90°
- 135°
- 180°
Correct answer: 4. 180°
- The RMS value and mean value is the same in the case of which wave
- If all waves have same peak value then which of the following wave will have the highest RMS value
