Question

A inductance capacitance circuit is in the state of resonance. if the $C=0.1\mu F$ and $L=0.25$ Henry. Neglecting ohmic resistance of circuit what is the frequency of oscillations

• A. $1007Hz$
• B. $100Hz$
• C. $109Hz$
• D. $500Hz$

Answer 1

The correct option is A $1007Hz$

From the formula, the frequency of oscillation is

$f=\frac{1}{2\pi \sqrt{LC}}$

$=\frac{1}{2\pi \sqrt{0.25\times 0.1\times {10}^{-6}}}$

$=1007Hz$
