Radios often utilize a variable capacitor in series with an inductor to tune the circuit to a particular frequency. In a particular shortwave radio, the value of the inductor is L = 1.06 µH. What must be the capacitance (in pF) of the circuit so that the radio is tuned to a frequency of f = 6.23 MHz?
