Question

Which equation correctly represents the Ampere-Maxwell law? Here I denotes conduction current.

G1 Physics · Accepted Answer

Ampere's original circuital law contained only the conduction-current term. Maxwell added the term produced by a changing electric flux: displacement current = ε₀ dΦₑ/dt. Therefore the complete Ampere-Maxwell law is ∮B·dl = μ₀[I + ε₀(dΦₑ/dt)], where I is the conduction current through the chosen surface. Correct option: B.
