For sinusoidal current the mean power over full cycle is 1/2 peak power Is this true?
For a sinusoidal current is the mean power over full cycle is half the peak power? This is a quote from a textbook however I thought that with sinusoidal graphs you always divided by root 2 for mean power?
Average Power is IrmsVrms and the rms I is Io/√2 and rms V is Vo/√2
Average Power is VoIo/2
Average Power is VoIo/2
Stonebridge
Average Power is IrmsVrms and the rms I is Io/√2 and rms V is Vo/√2
Average Power is VoIo/2
Average Power is VoIo/2
Okay cheers so would Irms²=½Io²
Freerider101
Okay cheers so would Irms²=½Io²
Irms = Io/√2
Irms² = Io/√2 x Io/√2 = Io²/2
So, yes
