An LC circuit in an AM tuner, such as that in a car radio, consists of a 2.1-mH inductor and a variable capacitor. The oscillation frequency of the circuit needs to be adjustable over the AM broadcast band from 540 to 1600 kHz. Find the capacitance, in picofarads, that will tune the circuit to the lowest frequency, 540 kHz, of the AM band.
