Gerry said:Interesting theory - first time I've heard of semiconductors doubling as dielectrics.
The free-wheeling diode will delay the drop-out of the solenoid because it provides a path for current generated by the collapsing magnetic field to circulate through the coil in the same direction as when the circuit is energised.
I was thinking in theory what a capacitor was, two conductors separated by a non-conductive material. I seem to recall from my '70s electronics training about something with diodes where the gap between cathode and anode increases with something voltage increases ..blah blah ....brain getting .. foggy....where are my keys?
