Type: MCQ-conceptual-Medium-Class 12
An AC source is connected to a capacitor C. Due to decrease in its operating frequency:
A
displacement current increases.
B
displacement current decreases.
C
capacitive reactance remains constant.
D
capacitive reactance decreases.
Correct Answer
Option B
Detailed Explanation
Capacitive reactance X_c = rac{1}{2\pi fC} increases as frequency decreases. This leads to a decrease in current, including displacement current.
