117.An L-C resonant circuit contains a 400 pF capacitor and an inductor of 400 μH. It is coupled to an antenna. Wavelength of
radiated electromagnetic wave is
- A 754 m
- B 377 m
- C 377 cm
- D 796 m
Answer & Solution
Correct Answer
(A) 754 m
Step-by-step Solution
Detailed explanation
Given, capacitance, C = 400 pF Inductance, \(L=400 \mu \mathrm{H}\) Frequency of resonating \(L C\)-circuit, \(f=\frac{1}{2 \pi \sqrt{L C}}\) Wavelength \((\lambda)=\frac{\text { Velocity }(c)}{\text { Frequency }(f)}\) \(\Rightarrow\) Wavelength,…
