An L-R-C series circuit is connected to an ac source of constant voltage amplitude V and variable angular frequency ω. Using the results of Problem 31.49, find an expression for (a) the amplitude VL of the voltage across the inductor as a function of ω and (b) the amplitude VC of the voltage across the capacitor as a function of v. (c) Graph VL and VC as functions of v for V = 100 V, R = 200 Ω, L = 2.0 H, and C = 0.50 μF. (d) Discuss the behavior of VL and VC in the limits v = 0 and For what value of v is VL = VC? What is the significance of this value of ω?
