I apologize if this question is a bit confusing, but I am studying electrical engineering and what keeps baffling me is why when you run current through an inductor then place an open in the circuit how come the Back EMF current is able to cause a spark across the open. I get that the inductor stores the electric energy in its magnetic field but how does that back current for a brief time constant not care about resistance and create a high potential difference or voltage to keep that current constant for a brief moment in time.
