Displacement current is continuous.
Correct answer: A. When the electric field is changing in the circuit
- A. When the electric field is changing in the circuit
- B. When the magnetic field is changing in the circuit
- C. In both types of fields
- D. Through wires and resistance only
Explanation
Displacement current was proposed by Maxwell and is not a flow of charge, but rather a term proportional to the rate of change of electric flux (dΦ /dt). It exists wherever there is a time-varying electric field, such as between the plates of a charging capacito

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
