In an LC oscillator, if the value of L is increased four times, the frequency of oscillations is __________?
Correct answer: D. Decreased 2 times
- A. Increased 2 times
- B. Decreased 4 times
- C. Increased 4 times
- D. Decreased 2 times
Explanation
For an LC oscillator, f = 1/(2π√LC). Increasing L fourfold makes √L twice as large, so the oscillation frequency becomes half its original value.
