Would AC power = VxIxSin Φ be more accurate than Cosine Φ ?

CliveS

 Faraday and Maxwell both agree that voltage must be at right angles to flux/current for real power. 

This should help physicists and mathematicians to demystify electricity and electromagnetic light.

    Er, so when V & I are in phase - i.e. phase angle between them is zero, while cos zero = 1, sine zero = zero - suggesting zero power factor (instead of 1) and so no power at all?

    Exactly so Andy. If the winding of a synchronous generator were in phase then only Var's would be produced as you need to cut the magnetic field at right angles.

    I'm confused then Clive - are we measuring the same thing with Φ then?
