Does Reactive Power flow between Energy storage elements in a three phase system?
I noticed that unlike the single phase ac power sources, the power in three phase is constant which means the instantaneous power is the same as the real power which is $$3V_{rms}I_{rms}\cos{\theta}$$ … power is present in the instantaneous power. …

Transformer magnetizing inductance
I am learning about transformers and in the equivalent circuit the magnetizing inductance of the excitation branch is supposed to represent the current needed to "set up" the flux in the core due to f …
