2pfr x R
R / 2pfrL
2pfrL / R
R2/2pfrL
Answer is Right!
Answer is Wrong!
The correct answer is: C. 2pfrL / R
The Q factor of an LC circuit is a measure of its quality. It is defined as the ratio of the energy stored in the inductor to the energy dissipated in the resistor per cycle. The higher the Q factor, the more efficient the circuit is at storing and releasing energy.
The Q factor can be calculated using the following formula:
Q = 2ÏfL / R
where:
- f is the frequency of the oscillation
- L is the inductance of the inductor
- R is the resistance of the resistor
Option A is incorrect because it does not include the inductance of the inductor. Option B is incorrect because it does not include the resistance of the resistor. Option D is incorrect because it does not include the frequency of the oscillation.
