Ampere's Law — Displacement CurrentHardQuestion 20221
Question
Maxwell added the displacement current term to Ampere's law to account for:
- ACurrent through a resistor
- BChanging electric flux in a region with no conduction currentCorrect
- CFriction in magnetic domains
- DEddy current losses
Correct answer
Changing electric flux in a region with no conduction current
Explanation
Between charging capacitor plates, no conduction current flows but a changing E field exists. Maxwell added id = ε₀(dΦE/dt) to resolve the inconsistency in Ampere's law and to predict electromagnetic waves.
