While out on an expedition by boat in the Pacific, you need to radio home to let them know you are safe. The LRC circuit in your radio transmitter has a 252 μH inductor whose coil has a resistance of 42Ω.The resistance of the rest of the circuit is negligible 1. To what value of capacitance would you adjust your variable capacitor to broadcast at 1450kHz? 2. What is the capacitive reactance (XC) at this frequency? 3. What is the inductive reactance (XL) at this frequency? 4. What is the impedance (Z or total AC resistance) of the circuit at this frequency?
