Question

Find the true statement.

(a) Displacement current and conduction current are never equal

(b) The current that flows through connection wires is called conduction current

(c) During charging of the capacitor, in the connection wires, conduction current is discontinuous and displacement current is continuous

(d) During charging of the capacitor, in the gap between the capacitor plates, conduction current is continuous and displacement current is discontinuous

The question was posed to me by my school principal while I was bunking the class.

Question is taken from Displacement Current in portion Alternating Current of Physics – Class 12

Answer 1

The correct choice is (b) The current that flows through connection wires is called conduction current

For explanation I would say: The true statement is ➔ the current that flows through the connection wires is called conduction current. All the other statements are not valid. Displacement current and conduction current can numerically be equal. During charging of the capacitor, in the connection wires, conduction current is continuous and displacement current is discontinuous. Similarly, during the charging of the capacitor, in the gap between the capacitor plates, conduction current is discontinuous and the displacement current is continuous.
