An L-C resonant circuit contains a `100 muF` capacitor an a `400 muH` inductor. It is not set into oscillation coupled to an antenna. Find the frequency of the radiated electromagnetic waves.

Text Solution

Verified by Experts

Given, `C = 100 pF = 100 xx 10^(-12) F, L = 400 muH`
` L = 400 xx 100^(-6) H`
Frequency of radiated EM wave is
`v = (1)/(2pisqrt(LC)) = (1)/(2 xx 3.14sqrt(400 xx 10^(-6) xx 100 xx 10^(-12)))`
`= 0.0796 xx 10^(7) Hz`
