Capacitor: Discharge
Image of page 4
Capacitor Discharge The fringe field of the capacitor plus the electric field of the charges on the surface of the wires drive current in a way to REDUCE the charge of the capacitor plates. Recall that we derived an expression for the fringe field by considering the superposition of two charged disks separated by a distance s. We ignored the small amount of charge on the exterior of the capacitor. See Lecture 8 Part 1 notes.

Fringe field of a capacitor rises until E =0 in a wire – static equilibrium. Fringe field opposes the flow of current! Capacitor: Charging
Image of page 6
Capacitor: Charging Ultimately, the fringe field of the capacitor and the field due to charges on the wire are such that E=0 inside the wire. At this point, i =0.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
