Pyq- Electromagnetic Induction & Alternating Currents L-6

Question: An ac source is connected to a capacitor C. Due to decrease in its operating frequency (NEET-2023)#

A) Displacement current increases.

B) Displacement current increases.

C) Capacitive reactance remains constant.

D) Capacitive reactance decreases.

Displacement current increases.#

Explanation#

$\mathrm{i}{\mathrm{C}}=\mathrm{i}{\mathrm{D}}=\frac{\mathrm{V}{\mathrm{O}}}{\mathrm{X}{\mathrm{C}}} \sin \omega \mathrm{t}$

$\mathrm{i}{\mathrm{C}}=\mathrm{i}{\mathrm{D}}=\left(\mathrm{V}_{\mathrm{O}} \omega \mathrm{C}\right) \sin \omega \mathrm{t}$

On decreasing frequency $i_C \downarrow$
