A Radio Tuning Circuit
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 4.18 .
Part A
What is the inductance of a coil connected to this capacitor if the oscillation frequency of the L-C circuit is 1.50 , corresponding to one end of the AM radio broadcast band, when the capacitor is set to its minimum capacitance?
Hint A.1 Frequency of an L-C circuit
Hint not displayed
Hint A.2 Angular frequency and cycles per second
Hint not displayed
Express your answer in henrys to three significant figures.
ANSWER: = Answer not displayed
Part B
The frequency at the other end of the broadcast band is 0.549 . What is the maximum capacitance of the capacitor if the oscillation frequency is adjustable over the range of the broadcast band?
