Displacement-Current-By-Prof-K-Thyagarajan
1 : Importance in Electromagnetism
Solution :
Recognize the role of displacement current in making Maxwell’s equations consistent and in predicting electromagnetic waves.
2 : Relation with Electric Field
Solution :
Displacement current occurs in regions where there is a time-varying electric field, such as between the plates of a charging capacitor.
3 : Distinction from Conduction Current
Solution :
Know that unlike conduction current, displacement current does not involve physical movement of charge.
