QUESTION 17* This and the next two questions concern the following situation: A series RLC circuit is driven by a sinusoidal voltage generator. It is shown in the figure below. The resistance is 200 2. The maximum voltage amplitude supplied by the voltage generator Vc is 141 V. The voltage VR across the resistor is measured to be VR = 100 cos(1000mu) volts. The voltages measured across the resistor and the voltage generator as functions of time are also sketched below. In particular, it is found that the voltage across the generator lags the voltage across the resistor. The frequency f produced VR 1 by the generator is: O(a) 500 Hz O(b) 1000 Hz 200 Q O(c) 1500 Hz O(d) 250 Hz B R (e) 100 Hz VG = VB-VA L C QUESTION 18* The reactance (X = Xz-Xc) of the circuit is O(a) positive. O(b) negative. O(c) zero. QUESTION 19*# The time-averaged power supplied by the generator is: O(a) 100 W O(b) 70.5 W O(c) 50 W O(d) 35.25 W O(e) 25 WQUESTION 20+ This and the next two guestions concern the following situation: A sinusoidal voltage generator drives a series RLC R circuit as shown in the figure below.
