Hi
Please have a look on the attachments. The question "Q" is about the diagram on this page. I don't understand why the voltage on the inductor goes to -2.5V when the square wave is at 0V. The square wave was pushing the current in clockwise direction before it jumped to 0V, so the inductor would try maintain the current in the same direction which means the same polarity as the square wave generator. Please help me with it. Thanks.
