AP EAMCET · PHYSICS · Alternating Current
The natural frequency of an \(L-C\) circuit is \(125 \mathrm{kHz}\). When the capacitor is totally filled with a dielectric material, the natural frequency decreases by \(25 \mathrm{kHz}\). Dielectric constant of the material is nearly
- A \(3.33\)
- B \(2.12\)
- C \(1.56\)
- D \(1.91\)
Answer & Solution
Correct Answer
(C) \(1.56\)
Step-by-step Solution
Detailed explanation
The natural frequency, \(f_{\mathrm{N}}=\frac{1}{2 \pi \sqrt{K L C}}=\mathrm{Fe}\) When capacitor is totally filled with dielectric material of dielectric constant \(\mathrm{K}\) then capacitance \(\mathrm{C}^{\mathrm{C}}=\mathrm{KC}\)…
