Conduction and Displacement Current – Rankers Physics

Ampere's Law and Displacement Current: Practice Problem & Solution

Assertion (A): Conduction and displacement current may be present in the same region of space. Reason (R): There is no perfectly conducting or perfectly insulating medium.  
Both (A) \(&\) (R) are true and the (R) is the correct explanation of the (A)
Both (A) \(&\) (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Ampere's Law and Displacement Current. Understanding the underlying formula is key to arriving at the correct answer below:

In a real dielectric medium with some conductivity, both conduction current (due to charge movement) and displacement current (due to changing electric fields) can exist simultaneously. As no material is perfectly conducting or insulating, this coexistence is possible.
