In L-C-R, A.C. series circuit, L = 9 H, ...

In L-C-R, A.C. series circuit, L = 9 H, R = 10`Omega` & C = 100`mu`F. Hence Q-factor of the circuit is _____.

A

25

B

45

C

35

D

30

Text Solution

Verified by Experts

The correct Answer is:
D
`Q = 1/R sqrt((L)/(C)) =(omega_0 L)/(R)`
`Q= 1/(10) sqrt((9)/(100 xx 10^(-6))) = 3/(10 xx 10^(-2)) = 30`
