... 1. Given a 7.4 pF air-filled capacitor, you are asked to convert it to a capacitor that can store up to 7.4 J with a maximum potential difference of 652 V. What is the dielectric constant of the dielectric you need to use to fill the gap in the capacitor? 2. Two parallel plates of area 100 cm2 are ...
