Ampere's Law — Displacement CurrentHardQuestion 20221

Question

Maxwell added the displacement current term to Ampere's law to account for:
  1. A
    Current through a resistor
  2. B
    Changing electric flux in a region with no conduction current
    Correct
  3. C
    Friction in magnetic domains
  4. D
    Eddy 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.
