Question

An LC circuit has L = 25 mH and C = 100 μF. Its resonance frequency is approximately:
  1. A
    100.7 Hz
    Correct
  2. B
    1000/π Hz
  3. C
    100/π Hz
  4. D
    10 Hz

Correct answer

100.7 Hz

Explanation

f=1/(2πLC)=1/[2π(0.025)(10−4)]≈<strong>100.7 Hz</strong>f=1/(2π\sqrt{LC})=1/[2π\sqrt{(0.025)(10^{-4})}]≈<strong>100.7\text{ Hz}</strong>.
