Transcribed Image Text:Part A
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 4.14 pF
What is the inductance L of a coil connected to this capacitor if the oscillation frequency of the L-C circuit is 1.63 MHz, corresponding to
one end of the AM radio broadcast band, when the capacitor is set to its minimum capacitance?
Express your answer in henrys to three significant figures.
