Description of Displacement Current: The concept of displacement current was first introduced by Maxwell purely on the theoretical ground. Maxwell postulates that "It is not only current in a conductor that produces a magnetic field but a changing electric field (or time varying electric field) in vacuum or in dielectric also produces the magnetic field.

6 FAQs about [Displacement current of a spherical capacitor]
What is displacement current in a capacitor?
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. Next, this displacement current is related to the charging of the capacitor.
How do you find the displacement current density of a capacitor?
Under the assumption of a uniform electric field distribution inside the capacitor, the displacement current density JD is found by dividing by the area of the surface: where I is the current leaving the cylindrical surface (which must equal ID) and JD is the flow of charge per unit area into the cylindrical surface through the face R.
How do you find the capacitance of a spherical sphere?
The capacitance for spherical or cylindrical conductors can be obtained by evaluating the voltage difference between the conductors for a given charge on each. By applying Gauss' law to an charged conducting sphere, the electric field outside it is found to be Does an isolated charged sphere have capacitance? Isolated Sphere Capacitor?
What is an isolated sphere capacitor?
Isolated Sphere Capacitor? An isolated charged conducting sphere has capacitance. Applications for such a capacitor may not be immediately evident, but it does illustrate that a charged sphere has stored some energy as a result of being charged. Taking the concentric sphere capacitance expression:
What is displacement current density?
Displacement current density has the same units as electric current density, and it is a source of the magnetic field just as actual current is. However it is not an electric current of moving charges, but a time-varying electric field.
Did Maxwell add displacement current to Ampère's circuital law?
Maxwell added displacement current to the electric current term in Ampère's circuital law. In his 1865 paper A Dynamical Theory of the Electromagnetic Field Maxwell used this amended version of Ampère's circuital law to derive the electromagnetic wave equation.
