An LC circuit with L = 55 mH is used in a radio to determine the frequency of a selected radio station. The station’s frequency is equal to the resonant frequency of the circuit.
(a) The radio is initially set for a frequency f = 1.05 MHz. What is the value of C?
(b) This capacitance is then increased by 10%. What is the new resonant frequency?
(c) Can you calculate the answer to part (b) without first finding the value of C in part (a)?
