PHYS 1502Q Chapter Notes - Chapter 22: Displacement Current, Electric Flux, Plane Wave
Document Summary
Faraday"s law e l b. Maxwell pointed out that the equations written are inconsistent with the conservation of charge and offered a modification to ampere"s law. Maxwell modified ampere"s law so that the enclosed current will always be numerically equal to the real current i for any bounding surface. D = (cid:541)0 enclosed + (cid:541)0 displacement. The current that charges the capacitor produces an electric flux in the region between the. Modified ampere"s law considers real currents and displacement current. Displacement currents, which are proportional to the time rate of change of the electric flux, can also produce magnetic fields. Current in a wire and a changing flux between the plates of a capacitor are related dq. In the wire, it refers to the charge that flows past any point per unit time. In the capacitor, it refers to the charge plowing onto the positive plate, and hence off the negative plate per unit time.
