Consider the circuit in picture
Suppose that I measure VA and VB with respect to GND using an oscilloscope.
Will VA and VB be in phase or out of phase with respect to each other?
Edit : I tried to make measurement on a real circuit with the values of parameters as in picture (V1 is 220V). I measured VA and VB with an oscilloscope and I got
I used the MATH function on oscilloscope to get the difference VA-VB
VA-VB= 20 V
I did not measure directly the phase shift between VA and VB signals, but, from the amplitude I can deduce that pase shift d was such that
Solving I find d around 106°.
Is this normal? I expected a 180° shift while I get a value which is much lower
