    Parallel Plate Capacitor Conundrum

    Now to work out at what voltage the air will breakdown and discharge. The breakdown strength of air is 3 MV/m, right? This maybe too simplified but can I do the following? distance between plates = 0.02 m breakdown voltage of air over 0.02 m is 3M * 0.02 = 60,000 V...

    Parallel Plate Capacitor Conundrum

    Yep figured the first bit. It becomes a simple voltage divider circuit. http://upload.wikimedia.org/wikipedia/en/f/f4/Impedance_Voltage_divider.png k1=1.0006 k2=6.0 Vout = [Z2/(Z1+Z2)]*Vin Zx = 1/j\omegaCx - Sub in for each Z Cx = kx * ε0*A/d - Sub in...

    Parallel Plate Capacitor Conundrum

    Homework Statement Hi everyone, I'm new here at posting but have found this forum very useful in the past. I have hit a snag with a capacitor problem... any thoughts? Assume you have a parallel plate capacitor separated by one cm of air and one cm of a dielectric with a dielectric constant of...
