A variable frequency a.c source is connected to a capacitor. How will the displacement current change with a decrease in frequency?

Current through the capacitor is directly proportional to impedance.  I∝Xc​ The impedance of a capacitor is Xc​=ωC1​ So, I∝ωC1​ The angular frequency ω is given as: ω=2πf ⇒I∝2πfC1​ Hence decrease in the frequency f of a.c. source decreases the conduction current. So there will be a decrease in the displacement current in the circuit.
