Displacement current
Displacement current is a concept in electromagnetism that was introduced by James Clerk Maxwell in his equations describing the behavior of electric and magnetic fields. It is a term used to explain the relationship between changing electric fields and magnetic fields.
Displacement current arises when there is a time-varying electric field in a region of space. It is a mathematical construct that accounts for the changing electric field’s ability to create a magnetic field, similar to how a current in a wire generates a magnetic field. Displacement current is represented by the symbol “I_d” and is included in Maxwell’s equations to ensure their consistency with experimental observations.
The presence of displacement current is particularly significant in situations involving changing electric fields and electromagnetic waves. It plays a crucial role in the understanding of phenomena such as the propagation of light and the behavior of capacitors in alternating current circuits.
Overall, displacement current is a key concept in electromagnetism that helps explain the interplay between changing electric and magnetic fields, contributing to our understanding of various electromagnetic phenomena.
The syllabus for the Advanced Course AIIMS in Physics does not provide specific details about “displacement current.” However, displacement current is a concept in electromagnetism that was introduced by James Clerk Maxwell. It is a term used to describe a changing electric field that creates a magnetic field, similar to how a current in a wire creates a magnetic field. Displacement current plays a crucial role in Maxwell’s equations and the understanding of electromagnetic waves.
