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 V
