Two 10-cm-diameter metal plates 1.0 cm apart are charged to ±12.5 nC. They are suddenly connected together by a 0.224-mm-diameter copper wire stretched taut from the center of one plate to the center of the other.
a. What is the maximum current in the wire?
b. Does the current increase with time, decrease with time, or remain steady? Explain.
c. What is the total amount of energy dissipated in the wire?
