Radiowaves of wavelength `360` m are transmitted from a transmitter. The inductance of the coil which must be connected with capacitor of capacity `3.6 muF` in a resonant citcuit to receive these waves will be appoximatelyA. `10^(3)H`B. `10^(2)H`C. `10^(-4)H`D. `10^(-8)H`

Answer» Correct Answer - d
`lambda=(c)/(v)` and `v=(1)/(2pisqrt(LC))`
`:. lambda=c.2pisqrt(LC)`
`L=(lambda^(2))/(4pi^(2)c^(2)C)`
`((360)^(2))/(4xx(3.14^(2))xx(3xx10^(8))xx3.6xx10^(-6))`
`=10^(-8)` H
