If the supply voltages to a 3-phase, 4-wice system are balanced The three phase load currents must be balanced The load individual phases must have the same power factor The individual phase frequencies may vary The three phase load currents may not be balanced

In the analysis of any electric circuit, nodal analysis is the method of determining the potential difference or voltage between different nodes in an electric circuit. A node is a point where two or more branches connect each other. In the nodal analysi…
