An ac source is connected to a capacitor \( C \). Due to decrease in its operating frequency :

  1. A
    capacitive reactance decreases.
  2. B
    displacement current increases.
  3. C
    displacement current decreases.
  4. D
    capacitive reactance remains constant
View Answer & Solution

Correct answer · Option C

displacement current decreases.

Explanation

Capacitive reactance \( X_c = \frac{1}{2\pi f C} \). As frequency \( f \) decreases, \( X_c \) increases, leading to a decrease in circuit current and hence displacement current decreases.
