    Calculation of the energy from a pulse

    Maximum energy from the power supplier unit is 200 J/s which goes to the capacitor. there will be some losses in the wires but it can be neglected. the spark gap device (PerkinElmer’s OGP ceramic-metal overvoltage spark gaps) have a resistor inside which I don't know the R value for that. When...

    Calculation of the energy from a pulse

    The owner of the device told me they are exponential decay pulses. yes it gives high voltage pulsed electrical field (20 kV/cm) within the liquid material in a treatment chamber in a very short period of time (4 µs). Yes the discharge will happen at the breakdown voltage of the spark gap...

    Calculation of the energy from a pulse

    Let me to explain it better. I have these devices as you can see in the picture attached. The capacitor become charged up to 18.5 kV and releases the energy to the discharge switch and then the energy in form of pulses go through the electrodes in the chamber. I am asked to calculate the energy...

    Calculation of the energy from a pulse

    I don't have the curve actually, I guess I need to draw it and yes have the area under.

    Calculation of the energy from a pulse

    Hello I need help for a basic question (i am awful in physics) :confused: I have two capacitors in parallel when they are charged up (18.5 kV) they release the energy to a discharge device. The discharge device releases the energy in the form of electric pulses through two electrodes in a...
