An AM radio station picks up a 1000kHz signal with a peak voltage 5.0mV The tuning circuit consists of a 420pF capacitor in series with a variable inductor. The total resistance of the circuit is 0.250. a. To what value should the inductor be tuned to listen to this radio station? b. What is the peak current through the circuit at resonance? c. A competing radio station at 105OkHz produces a 10mV antenna signal. What is the current at this frequency in our receiver circuit tuned to 1000kHz?
