9.11 Displacement Current
9.11 Displacement Current. Earlier we have studied an interesting circuit which was consisting of a resister and a capacitor. We called that circuit as "RC circuit". Recall an RC circuit. In this circuit, we had a power supply, which generates ε volts of EMF, a switch, a resister, and a capacitor connected to that in series form.

Displacement Current
The displacement current explains why capacitors can pass alternating current—because the changing electric field between the plates of the capacitor generates a displacement current that can create a magnetic field and propagate the signal. Power Factor Correction: The displacement current is responsible for the leading nature of the …
The amount of displacement current inside a capacitor is directly proportional to its capacitance. This means that a capacitor with a larger capacitance will have a higher amount of displacement current when the electric field changes. Similar threads. Charge upon a parallel plate capacitor.

What is the formula for charging a capacitor with constant current?
$begingroup$ To achieve a constant current through a capacitor implies that the voltage across the capacitor increases without limit. In reality, "without limit" is limited by the capacitor exploding. 5 tau is generally taken to be "good enough" at 99.3% charged. $endgroup$ –

Capacitor and displacement current.
In a capacitor, displacement current is the flow of charge between the two plates through the insulating material. When a capacitor is charging or discharging, the electric field between the plates changes, causing displacement current to flow. This current is necessary for the capacitor to function and store energy.
electric fields
The value of the displacement current after the capacitor is charged ideally then we say equals the maximum value of the the conduction current during charge which actually is the value we get right on the start of the capacitor charging period (i.e charging current drops down to zero with time).

In the context of a charging capacitor, the current density arises due to the displacement current, which is not an actual flow of electrons but rather a changing electric field. The given exercise states that the current density of the displacement current between the capacitor''s plates is uniform and has a magnitude of 20 A/m².
