**Inductance of the coil??**

## Homework Statement

A radio has a tuning circuit consisting of a variable capacitor and antenna coil. IF the circuit has a maximum current when C=300pF and f=40kHz, what's the inductance of the coil??

## Homework Equations

f= 1/(2pi root (LC))

## The Attempt at a Solution

L=[1/(2pi(40000))]^2 times 1/(300E-12)

But, I didn't get the answer :52.8x 10^3 was the answer;;
