Hello.
I connect two different transformers to the same socket in my home.
I coonect each output to a resistor (different resistors though).
Using two probes and oscilliscope, i present on screen the two resistors' voltages at the same time.
I measure the phase (in seconds) between both signals, and calculate power factor:
Power_Factor = COS(2pi * Phase/Period).
What power factor should i expect?
Do transformers have quite large ESR and capacitance, meaning i should expect a Power_Factor that is not close to 1?
Thanks.
