Why did Maxwell introduce the concept of displacement current? Explain.

Explanation

Maxwell found that Ampere circutal law is
logically inconsistent. To make this law logically
consistant, Maxwell introduce the concept of
displacement current, which is known as
Ampere Maxwell's law as
`oint vecB.vec(dl)=mu_0(I+I_D)`
where I is the conduction current and `I_D` is the
displacement current. Here, `I_D=in_0dphi_E//dt`.
