Directions. Read each item carefully. Answer what is being asked. (5 points each number) 1. Discuss what would happen if a conducting slab rather than a diele were inserted into the gap between the capacitor plates. 2. Discuss how the energy stored in an empty but charged capacitor cha when a dielectric is inserted if (a) the capacitor is isolated so that its ch does not change; (b) the capacitor remains connected to a battery so the potential difference between its plates does not change
