NEET · Physics · STD 12 - 8. Electromagnetic waves
An ac source is connected to a capacitor \(C\). Due to decrease in its operating frequency :
- A capacitive reactance remains constant.
- B capacitive reactance decreases.
- C displacement current increases.
- D displacement current decreases.
Answer & Solution
Correct Answer
(D) displacement current decreases.
Step-by-step Solution
Detailed explanation
\(i _{ C }= i _{ D }=\frac{ V _{ O }}{ X _{ C }} \sin \omega t\) \(i _{ C }= i _{ D }=\left( V _{ O } \omega C \right) \sin \omega t\)
