Question : 3 of 9

Marks: +1, -0

SECTION -B

How is the equation for Ampere's circuital law modified in the presence of displacement current? Explain.

Solution:

Diagram
Explanation

\;∮ ↙{C_2} {B}↖{→} ⋅ {d l}↖{→}=µ_0 I

\;∮↙{C_2} {B}↖{→} ⋅ {d l}↖{→}=µ_0 (I_C+I_D)

There is an inconsistency in the Ampere's Circuital law.
Maxwell modified it to be

\;∮ {B}↖{→} ⋅ {d l}↖{→}=µ_0 (i_{ {\C}}+i_d)

\;\;\text " where "\; i_{ {\d}}= {\E}_{ {\o}} \;{d ϕ_{ {\E}}}/{d t}
