The total current in the Ampere Maxwell law is conduction current plus:
AAlternating currents
BPhotoelectric flow
CThermionic emission
DDisplacement current
Answer & Solution
Correct answer: D. Displacement current
1. Ampere's law needed a second source term to stay consistent.
2. That term comes from the changing electric field.
3. So the total is conduction plus displacement current.
4. The answer is displacement current.
