Direction: Answer the following questions below and box or highlight your final answer. Always write down the givens and convert into its SI unit if necessary. 4. A parallel plate capacitor has a capacitance of 349 nF, and a potential difference of 56 V between the plates. The charging battery is disconnected and a paraffin slab (k = 2.2) is inserted between the plates. (a) What is the potential energy of the device before and after the insertion of the slab? (b) What is the potential energy of the device before and after, if the inserted slab is a porcelain slab (k = 6)?
