A constant voltage at a frequency of `1 MHz` is applied to an inductor in series with variable capacitor, when capacitor is `500 pF`, the current has its maximum value, while it is reduced to half when capacitance is `600 pF`. Find
`Q` factor of the circuit is

A

10.4

B

20.8

C

5.2

D

9.4

Text Solution

Verified by Experts

The correct Answer is:
A
`Q = (omega_(0) L)/(R ) = (314)/(30.01) = 10.4`
