Question

2. “Doc” Brown’s flux capacitor can release 1.21 Giga Watts of power. Assume this is released in 1 second. Also assume the energy stored in a flux capacitor is calculated in the same way as the energy stored in a (normal) capacitor. Finally, assume the voltage in the capacitor is limited to 1kV. Calculate the capacitance required to store this much energy .

3. Recall for a capacitor ε is the permittivity of the dielectric used, ε = ε 0 ε r ε r = relative permittivity and εo = permittivity of vacuum Assume “Doc” Brown’s flux capacitor uses an alumina oxide dielectric which has 40 times the permittivity of vacuum and can achieve 1 mm spacing between plates. Further assume “Doc” can stack up 500 layers (i.e. parallel plates) of capacitors. Calculate the area (A) required for the capacitor in #2
