A transmitter transmits at a wavelength ...

A transmitter transmits at a wavelength of `30` meter. A condenser or capacitance `2.4 muF` is being used. The value of the inductance for the resonant circuit is approximately.

A

`10^(-4) H`

B

`10^(-6) H`

C

`10^(-8) H`

D

`10^(-10) H`

Text Solution

Verified by Experts

The correct Answer is:
D
`v=v/(lambda) =(3xx10^(8))/300 Hz=10^(6) Hz`
`v=1/(2pisqrt(LC)) impliesv^(2)=1/(4pi^(2)LC)`
or `L=1/(4pi^(2)v^(2)C)`
or `L=1/(4xx9.87xx10^(12)xx2.4xx10^(-6)) H`
`=(10^(-6))/(4xx9.87xx2.4)H=0.01xx10^(-6)H=10^(-8)H`.
