Answer: Equal to the conduction current.
- A Equal to the conduction current
- B Zero at every instant of time
- C Half the conduction current value
- D Twice the conduction current value
Correct answer: A. Equal to the conduction current
Explanation: Maxwell showed the displacement current I<sub>d</sub> = ε<sub>0</sub>(dΦ<sub>E</sub>/dt) between the plates exactly equals the conduction current in the connecting wires, keeping the current continuous.
In an electromagnetic wave, the oscillating electric field (E) and magnetic field (B) are perpendicular to each other and to the direction the wave travels - a purely transverse wave that needs no medium, unlike sound.
