The following three step process refers to a simple rc circuit with a battery and an initially open switch. recall that the charge on a capacitor is given by c -cve, and the energy stored in a charged capacitor is given by pe-½cp2 step the switch is closed, allowing the capacitor to charge. after the capacitor has charged, a slab of dielectric material is inserted between the plates of the capacitor and time passes. step 2: step 3 the switch is opened, and the dielectric is removed. which of the following describes the change in potential energy stored in the capacitor during cach step?
