Three Phase power calculation is a very important aspect for a budding Electrical Engineer.It is very important to understand the difference between three phase resistive,inductive and capacitance load.

The difference lies in the fact that the power factor that is generated by all the different loads.

In

Resistive Load- power factor is unity

Inductive Load- power factor is not unity

To understand the funcional difference between the two,you can learn more by watching the video
