After learning complex numbers for ac phase etc I have a question. If there are 2 sine waves out of phase they can be added and seen as a single waveform on a scope. My question is how do you know that there is more than one waveform when you connect the scope to the signal?
Second if current and voltage are 90 out of phase and you can see the voltage side on the scope what do you see the current side with to prove they are out of phase by 90?
Thanks
