- Radios use resonance in order to tune-in to a particular station. A physics student builds a simple radio using a RLC series circuit. They decide to use a resistor with R = 40.5 2 but they only have one capacitor with capacitance C = 215 pF. To listen to their favorite station KXY 84.1 FM, which is at a frequency of 84.1 MHz, what must be the inductance L of their circuit's inductor? When they tune-in to KXY 84.1 FM, they measure a rms current of 0.0380 A. What is the rms voltage Vrms across the circuit when they tune-in? L = H Vrms VThe following information applies to Questions 5 through 9. Maximum power from a radio transmitter is delivered to the load when the load impedance is equal to 50 ohms. Assume that when it is connected to a 50 ohm load, the transmitter delivers 100 watts. Imagine that the transmitter is connected to a 50 ohm load through a cable that is 100 ft long. The cable has a characteristic impedance of 50 ohms and a loss of 3 dB per 100 ft. How much power is now delivered to the matched load?
