AC circuit problem. Please answer all with work.

You MUST provide work to support your answers. Answers without supporting work will not receive any credit. The first four questions refer to the circuit shown to the right. An AC generator of unknown angular frequency omega produces a maximum voltage of epsilon_max = 20V. The inductance and the capacitance values appear on the figure. A student measures the maximum voltage drop across the inductor to be V_L,max = 10 V and measures the maximum voltage drop across the capacitor to be V_c,max = 5V. The maximum voltage drop across the resistor is: 19.5 V 15.0 V 16.8 V 5.0 V 20.0 V What is the angular frequency, omega, of the generator? 6325 rad/s 4472 rad/s 3162 rad/s 2236 rad/s This cannot be determined from the information given. By what angle phi does the generator voltage lead the current? How would you change the angular frequency omega to get the largest possible current, assuming that epsilon_max is held fitted at 20V? Increase omega Decrease omega A series RLC circuit is connected to a 60Hz AC generator which produces a maximum voltage of epsilon_max = 20V. The circuit element values are given below: Calculate the total impedance of the circuit L What is the phase relationship between the voltage of the AC generator and the voltage across the resistor? Is the generator voltage in phase with, leading, or lagging the voltage across the resistor?
