Two 10-cm-diameter metal plates 1.3 cm apart are charged to ±12.5 nC. They are suddenly connected together by a 0.234-mm-diameter copper wire stretched taut from the center of one plate to the center of the other. Part A: What is the maximum current in the wire? Part B: Does the current increase with time, decrease with time, or remain steady? Part C: What is the total amount of energy dissipated in the wire?
A capacitor consists of two 6.6-cm-diameter circular plates separated by 1.0 mm. The plates are charged to 170 V , then the battery is removed. How much energy is stored in the capacitor? How much work must be done to pull the plates apart to where the distance between them is 2.0 mm?

1. Parallel plates. You have two equal but oppositely charged parallel conducting plates, separated by 10 cm. A voltmeter shows that the potential difference between the plates is 500 V. (a) Which is at a higher potential, the positive or negative plate? (b) How big is the electric field between the plates? (c) You let go of an electron next to the negative plate. How much work does the electric field do in moving the electron to the positive plate?...
