A radio can be tuned into a particular station frequency by, Ask an Expert

Academics

A radio can be tuned into a particular station frequency by adjusting the capacitance in an L-C circuit. Suppose that the minimum capacitance of a variable capacitor in a radio is 4.18pF,

Part(a) What is the inductance L of a coil connected to this capacitor if the oscillation frequency of the L-C circuit is 1.69MHz , corresponding to one end of the AM radio broadcast band, when the capacitor is set to its minimum capacitance?

Part(b) The frequency at the other end of the broadcast band is 0.535MHz . What is the maximum capacitance C_max of the capacitor if the oscillation frequency is adjustable over the range of the broadcast band?
