1. Suppose you wanted to store 27 ?C of charge in a capacitor across a voltage of 120 V. What capacitance is needed in nF?
2. You are given a parallel plate capacitor that has plates of area 4.00 m2 which are separated by 0.0100 mm of nylon (dielectric constant ? = 3.4). You are told to assume that this capacitor stores 0.170 C of charge. Calculate what the applied voltage in kV should be for this capacitor.
