MCQ
The resonant frequency of an $L - C$ circuit is.
- ✓$\frac{1}{2\pi\sqrt{\text{LC}}}$
- B$\frac{1}{2\pi}\sqrt\frac{\text{L}}{\text{C}}$
- C$\frac{1}{4\pi}\sqrt\frac{\text{L}}{\text{C}}$
- D$\frac{1}{2\pi}\sqrt\frac{\text{C}}{\text{L}}$
✓
Answer
Correct option: A.
$\frac{1}{2\pi\sqrt{\text{LC}}}$
Resonance frequency f of an $L - C$ circuit can be written as
Resonance frequency $\text{f}=\frac{1}{2\pi\sqrt{\text{LC}}}$ where $L =$ inductance and $C$ is capacitance.
