Consider a series RLC circuit where R = 549 ? and C = 1.25 ?F. However, the inductance L of the inductor is unknown. To find its value, you decide to perform some simple measurements. You apply an ac voltage that peaks at 36.0 V and observe, using an oscilloscope, that the resonance frequency occurs at 39700 s-1. What is the inductance of the inductor in millihenrys?
