MHT CET · Physics · Alternating Current
With the gradual increase in frequency of an a. c. source, the impedance of an LCR series circuit
- A first decreases, becomes minimum and then increases.
- B increases.
- C decreases.
- D remains constant.
Answer & Solution
Correct Answer
(A) first decreases, becomes minimum and then increases.
Step-by-step Solution
Detailed explanation
With increase in frequency current increases initially, becomes maximum and then decreases with further increase in frequency.
