Maxwell Equations MCQs

Practice Maxwell Equations MCQs with four options, answers and explanations for focused Electronics & Telecommunication Engineering revision.

Question 1
Electromagnetic TheoryMaxwell Equations

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.
Reference: Standard electromagnetic theory: maxwell equations
Question 3
Electromagnetic TheoryMaxwell Equations

The Maxwell-Ampere equation in differential form is?

  • Acurl H = J + partial D/partial t
  • Bcurl E = J + partial D/partial t
  • Cdiv H = J
  • Ddiv D = J + partial B/partial t
Report an error
Correct Answer: A. curl H = J + partial D/partial t
Explanation: Maxwell-Ampere law is ∇×H=J+∂D/∂t.
