b) What is the capacitive reactance (Xc) at this frequency? (4 points, out of which 1 point is for the equation being used, and 1 point for the answer to 5 significant figures with the units).Q2) 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 225 uH inductor whose coil has a resistance of 35 0. The resistance of the rest of the circuit is negligible. Exam question. Do not share or post. a) To what value of capacitance would you adjust your variable capacitor to broadcast at 1425 kHz? (4 points, out of which 1 point is for the equation being used, and 1 point for the answer to 5 significant figures with the units)
