Bound current vs free current
Webis the net displacement current that passes through a small surface bounded by the curve C. The magnetic field between the plates is the same as that outside the plates, so the displacement current must be the same as the conduction current in the wires, that is, which extends the notion of current beyond a mere transport of charge. WebApr 10, 2024 · 8. Electric Current current = charge / time or I = q/t • Units: Amps (A) • An amp is the flow of 1 C of charge per second • NOTE: 1 C = the charge of. 9. Electric Current • Usually the number of electrons entering a wire is the same as the number leaving • This gives the wire a net charge of zero. 10.
