WebExpert Answer. 5. Displacement Current Through a Loop (1 point) A parallel plate capacitor is discharging so that the electric field between the two plates is E (t) = Ae−τ t, where A = 4 V/m and τ = 2 s. A circular loop with radius r = 5 cm is parallel to and between the two plates (the radius of the plates is much larger than the loop's). WebDischarging a Capacitor When the switch in Figure 10.38 (a) is moved to position B, the circuit reduces to the circuit in part (c), and the charged capacitor is allowed to discharge through the resistor. A graph of the charge on the capacitor as a function of time is shown in Figure 10.40 (a).

Webq=ϵC(1−e CR−t) where q is the charge on the capacitor at time t,CR is called the time constant, ϵ is the emf of the battery. Discharging: If the plates of a charged capacitor are connected through a conducting wire, the capacitor gets discharged. Again there is a flow of charge through the wires and hence there is a current.
