How to set up, put together, generate about 25kv high voltage using 1.5 -3 Millihenry inductor coil with 10amps current flow? Back Emf E volts = L Henries times change in current amps di divided by change in time dt second. Is that a 10Mhz solid state oscillator pulse needed with fast transistor? An ignition coil only shows 130 volts reverse volts with 4MH that runs the secondary side and that is in milliseconds , instead of microseconds. The value of .6 microsecond (10Mhtz) shows in formula for 25kv. The standard autotransformer output is not AC, and pulsing DC cannot use a multiplier circuit to raise up voltage. (Maybe it would be just easier to wrap wires around inductor to make a step up transformer as primary and secondary.) Doesn't the Tesla coil set up have an unusual step up ratio at resonance of Pr + Sec, without using standard turns ratio?
