What happens when a multi-phase source where the sources are not in phase is applied to a single load (I'm ignoring the impedance angle of the load for now)? Let's say I have a 3 phase source where the source angles are 120 degrees apart. However I do not connect source B. So I have source A at 0 degrees connected to the top of a single load, and I have source C at +120 degrees connected to the bottom of the load. What is happening with the two currents? They're out of phase so literally I picture them moving back and forth but not at the same time. Are the magnitude and angles of the two currents added together to form one current?
