An ac source is connected to a capacitor C. Due to a decrease in its operating frequency,

Asked in NEET 2023 · Capacitor on an a.c. source

Answer: (2) Displacement current decreases

Step-by-step solution

The capacitive reactance is X_C=1/(ω C), so lowering ω raises X_C.

The conduction current in the circuit is I=V/(X_C), which therefore falls.

Inside the capacitor there is no conduction current; the displacement current there is exactly

equal to the conduction current in the wires, so it falls with it.

The displacement current decreases.
