Explain why capacitance ?C depends neither on the stored charge ?q nor on the potential difference ?V between the plates of a capacitor. Capacitance is determined only by the physical properties of the capacitor. The stored charge ?q and the potential difference ?V are independent of the size and shape of the capacitor. The net charge on a capacitor is zero, and therefore the potential difference ?V cancels. The stored charge ?q is inversely proportional to the potential difference ?....

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...
