Re: 20 joules at 100 bps vs 4 joules at 500 bps

Friends,

Another huge mistake in the categorization of the so called displacement current.

Displacement currents only occur in dielectrics.

Never do displacement currents occur in conductors. The do not occur in metal conductors or plasma arcs or streamers. If a charge particle is capable of moving in a conductor then by definition it's not displacement current. Once charge particles, such as electrons or ions, are capable of moving in a streamer or arc channel then the resultant current is just plain old EM current.

Hi Boris,
At the risk of misinterpreting what has been said, consider a toroid that has been charged to the breakout point and at the instant breakout begins, imagine the secondary coil being totally removed. A streamer begins and lets say it still connects to ground. It seems the circuit is the capacitance of the toroid (to ground), the streamer impedance, and the return path carries the displacement current. The impedance mentioned below would now be infinite and yet the streamer and power arc would still occur. It seems that with the secondary in place, the impedance Z (below) would help with the recharging of the toroid and the sustainability of the arc.

To say that the circuit element connecting the toroid to ground is its capacitance, and to say that the return path is by displacement current are exactly the same thing. What exists in series with the streamer is a charged capacitor, with the secondary coil in -parallel- with it. If at the instant of the discharge there is no significant energy stored in other parts of the system than the terminal capacitance, the presence of the secondary coil would -reduce- the streamer current, by providing an alternative (although high-impedance) path to the current coming from the capacitor, instead of contributing to it.
