Question

The SI unit of $\frac{1}{2\pi \sqrt{LC}}$ is equivalent to that of :

• A. time period
• B. frequency
• C. wavelength
• D. wave number

Answer 1

The correct option is B frequency

The angular frequency of current oscillations in an LC circuit is given by $\omega =\frac{1}{\sqrt{LC}}$ and $\omega =2\pi f$.
$\Rightarrow f=\frac{1}{2\pi \sqrt{LC}}$ and the unit is equivalent to that of frequency.
