Electric Field due to a Uniformly Charged Disk (Fig. 7) Divide the disk into rings of radius r and thickness dr. If you cut the ring and pull it out into a rectangle, it has length 2 πr and thickness dr.
WebThe answer is that the source of the work is an electric field E → that is induced in the wires. The work done by E → in moving a unit charge completely around a circuit is the induced emf ε; that is, ε = ∮ E → · d l →, 13.9. where ∮ represents the line integral around the circuit.
