For L-C-R A.C. circuit resonance frequency is 5000 Hz and frequencies at half power points are 4950 Hz and 5050 Hz. The Q-factor is ……

A

100

B

0.02

C

`50`

D

0.01

Text Solution

Verified by Experts

The correct Answer is:
C
`Q=W_0/(DeltaW)=(2pif_0)/(2pi(f_2-f_1))`
`=f_0/(f_2-f_1)`
`=5000/(5050-4950)`
`=5000/100`
=50
