Displacement Current: Difference & Example

Click For Summary
Displacement current is not always equal to conduction current; it is a component of Maxwell's equations, specifically the Ampere-Maxwell Law. This law describes the relationship between electric fields, magnetic fields, and current densities. The discussion highlights the need for context when comparing displacement and conduction currents, as they serve different roles in electromagnetic theory. Participants are encouraged to provide specific examples to clarify their understanding of the relationship between these two types of currents. Understanding the distinction is crucial for grasping the fundamentals of electromagnetism.

Is displacement current always equals to conduction current?if not then can anyone give me an example for it?if yes,then can anyone prove it?

The socalled "displacement current" is a misnomer. It's not a current but it's simply part of one of Maxwell's equations, the Ampere-Maxwell Law, which reads in Heaviside-Lorentz units
$$\vec{\nabla} \times \vec{B}-\frac{1}{c} \partial_t \vec{E}=\frac{1}{c} \vec{j}.$$
This is the "microscopic form" of the law, and ##\vec{j}## is the total current density.

The source of the electromagnetic field are charge and current densities.
 
I think you should tell us some details about the context or background or origin of your question. Do you have a specific example in mind, where the two currents are equal?
