A resistor of R = 6`Omega`, an inductor of L=1 H and C = 17.36 `muF` are connected in series with an A.C. source. Find the Q-factor.

A

2.37

B

80

C

3.72

D

40

Text Solution

Verified by Experts

The correct Answer is:
D
`Q=1/R sqrt(L/C)`
`=1/6sqrt(1/(17.36xx10^(-6)))=1/6sqrt(10^8/1736)`
`therefore Q=1/6xx10^4/41.66` = 40.006
`therefore Q approx 40`
