120 degree phase differenc between each connection
120 degree between all phases
C.120 Deg.
It's120 degrees for sure =360 / number of phases
The formula for phase difference in voltage is:360/total number of phases
We have3 phase system, so360/3 =120 degree.
Hence3 phase system has120 degree phase difference in voltages, so they are equally spaced.
Answer: C, 120 degree
