- Lecture 45: Why Is This Circuit Unbalanced?
In this video I will explain what causes 3-phase circuit to be unbalanced. An unbalanced circuit is cause by an unbalanced source or an unbalanced load. 1) the source voltages are not equal; 2) the source voltage phases are not equal; 3) the load impedances are not equal.
