(a) An RLC circuit is used in a radio to tune into an FM station broadcasting at f = 99.7 MHz. The resistance in the circuit is R = 10.0 N, and the inductance is L = 1.80 pH. What capacitance (in pF) should be used? 1.4157 pF (b) What If? What would be the range of capacitances (in pF) needed to cover the entire FM band, from 88.0 MHz to 108 MHz? Cmin = 1.8171 Cmax = 1.87 x PF X pF
