What is the role of reactive power in a electric circuit?

Some electrical machines work on the principle of electromagnetic induction. For such events to occur, we need inductor due to which reactive power flows in the circuit. Since, this power is due to the energy storing elements in the circuit like inductor and capacitor.

That is why, we need reactive power in a electric circuit.

To supply the reactive power demand of load and to regulate of output volage at the grid.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
