It doesn’t matter about my words the fact remains the same about the scope and the 180 degrees out of phase. The laws of physics remain true and there is no way possible that the two ends of a single phase winding to be 180 degrees out of phase with each other.
It doesn’t matter what one tries to prove using the picture of a scope especially if they don’t understand vector math, the fact remains that the two ends of a single phase winding are in phase with each other.
If you cannot agree that this picture of an oscilloscope shows channel A being 180 degrees out of phase with channel B, then your use of words differs from the norm.
It doesn’t matter what someone has read or been told all that matters is the laws of physics which prove the fact that using a scope to look at the sine wave of a center tap winding shows that the winding is in fact in phase with each other
I am confident that we both know how the voltages on the two hot legs on a 120/240 AC breaker box relate to each other and the ground/neutral. There is no argument on the underlying physics.
and there is no way possible that the two 120 volt sine waves are 180 degrees out of phase with each other.
It's a terminology thing. Do you don't seem buy into the normal terminology.
Here is a list of statements. Which is the first in the list that you disagree with?
1. A voltage is measured at one point with respect to another point.
2. Measuring the vector, complex, time-domain or frequency domain voltages on 120 VAC hot lines
with respect to the grounded wires is the common way. (sorry about the long drawn out wording, but wanted to avoid ambiguities)
3. That way is reasonable.
4. Two sine waves that have their most positive instantaneous voltage occur at the same time can be said to be in phase.
5. Presuming the same frequency for both and presuming a common reference point, a sine wave observed on one wire that has its most positive instantaneous voltages occur at the same time as the most negative instantaneous voltages occur on a different wire , the voltages would be described as out of phase with each other.
6. The oscilloscope picture shown shows two out of phase (180 degrees out of phase) sine waves.
