The frequency of the output signal of an LC oscillator circuit is ' F ' Hz with a capacitance of 0.1. If the value of the capacitor is increased to 0.2, then the frequency of the output signal will be (a) F/√(2) Hz (b) F/√(3) Hz (c) F/2 Hz (d) 2F Hz

Answer: (a). F ∝ 1/√(C) C doubles: F' = F/√(2) So the answer is (a).

LC Oscillations

The frequency of the output signal of an LC oscillator circuit is ' $F$ ' Hz with a capacitance of 0.1 $\mu\text{F}$ . If the value of the capacitor is increased to $0.2\ \mu\text{F}$ , then the frequency of the output signal will be

Show answer and solution

Answer: (a)

$F \propto \frac{1}{\sqrt{C}}$
$C$ doubles: $F' = \frac{F}{\sqrt{2}}$
So the answer is (a).
