Which one of the following current flows in the gap between the capacitor plates?(a) Displacement current(b) Conduction current(c) Resistive current(d) Total currentThe question was asked by my college director while I was bunking the class.I want to ask this question from Displacement Current in division Alternating Current of Physics – Class 12

Answer»

The correct answer is (a) Displacement current

To ELABORATE: Displacement current (ID) is the ELECTRIC current that flows in the gap between the PLATES of the capacitor during its charging, which originates due to the time-varying electric field in the space between the two plates of the capacitor. The expression for displacement current is given as:

ID = εo \(\FRAC {d\Phi_{\varepsilon}}{dt}\)
