Question

Problem: A parallel-plate capacitor is constructed using a dielectric material whose dielectric constant is 2.00 and whose dielectric strength is 5.00 x  10⁸ V/m. The desired capacitance is 0.400 µF, and the capacitor must withstand a maximum potential difference of 4.00 kV.

Part A: Find the minimum area of the capacitor plates.
