Solution

Q.
An AC source is connected to a capacitor C. Due to decrease in its operating frequency [2023]

1 displacement current decreases

2 capacitive reactance remains constant

3 capacitive reactance decreases

4 displacement current increases

Ans.
(1)

Capacitive inductance, $X_{C} = \frac{1}{2 π f C}$

As frequency decreases, $X_{C}$ increases.

So, conduction current decreases. Hence, displacement current decreases.

Solution

Q. An AC source is connected to a capacitor C. Due to decrease in its operating frequency [2023]

1 displacement current decreases

2 capacitive reactance remains constant

3 capacitive reactance decreases

4 displacement current increases

Ans. (1) Capacitive inductance, XC=12πfC As frequency decreases, XC increases. So, conduction current decreases. Hence, displacement current decreases.
