QuEsTiOn-2

Q2)Can we get an inductor current in square wave form?? if yes ,how?
Note: Inductor doesnt allow the sudden change in current through it.

  1. Yes you could actually make the inductor current become a square wave but not a perfect one. It depends on where you place the inductor. Ann inductor on a source side or a source inductors current cannot be made zero because any attempt to do so would induce triplant harmonics which are pity devastating to the supply and grid. But if the inductor is on the load side you could make it go to zero. It is true that Inductor does not allow sudden changes in load. Better put as an electrical engineer, an inductor voltage follows what is known as a volt-second balance. By varying this volt second balance i.e. putting a dc voltage source as the load end we could manage to produce a sudden change in current in an induct but then again you are dealing with large voltages which should be sustained by the load.
