I've been experimenting with inductive kickback by connecting an inductor to a battery and a multimeter in series - when disconnecting/connection it generates a pulse of at least 20v. However, when I charge up several capacitors (in parallel) and connect them in series (to multiply the voltage) (also in series with inductor and multimeter), there is no pulse and no spark - despite the fact the same amount of current and several times the voltage of the battery should be being discharged.
I'm aware that the "kickback" voltage is proportional to the rate of change of current - however, why is there no spark when I connect the capacitor bank and the current shoots up?
