For L-C-R AC circuit, resonance frequency 5000 Hz and frequencies at half power points are 4950 Hz and 5050 Hz . What will be the Q-factor ?
- A 100
- B 0.02
- C 50
- D 0.01
Answer & Solution
Correct Answer
(C) 50
Step-by-step Solution
Detailed explanation
(C) 50
\(\mathrm{Q}=\frac{\omega_{0}}{\Delta \omega}=\frac{\omega_{0}}{\omega_{2}-\omega_{1}}\)
\(\mathrm{Q}=\frac{5000}{5050-4950}=\frac{5000}{100}=50\)
\(\mathrm{Q}=\frac{\omega_{0}}{\Delta \omega}=\frac{\omega_{0}}{\omega_{2}-\omega_{1}}\)
\(\mathrm{Q}=\frac{5000}{5050-4950}=\frac{5000}{100}=50\)
