This video by Dr. Ali Shirsavar from Biricha is a follow up from a previous video on inductor behaviour in a switching power supply with practical demonstration of inductor EMF electromotive force.
In one of our previous videos here: Inductor Behaviour in a Switching Power Supply we explained the action of an inductor in a switch mode power supply.
This is the second part of our introductory videos about inductors.
In this video, we will demonstrate just how big an inductor back EMF can get even when energised with a tiny battery. By simply breaking the current path of an inductor we light up, albeit momentarily, a 230V lightbulb with a single PP3 9V Battery.
