Maxwell introduced displacement current primarily to extend which law to time-varying fields?

  • AAmpere's circuital law
  • BCoulomb's law
  • CGauss's magnetic law
  • DBiot-Savart law for static point charges
Report an error
Correct Answer: A. Ampere's circuital law
Explanation: The displacement-current term makes Ampere's law consistent with charge conservation in time-varying electromagnetic fields.
