1. Because the circuit below stores energy in the capacitor and in the magnetic field of the inductor and the energy is simply transferred back and forth on alternate half-cycles, this circuit is commonly called a

2. Using the circuit below, create a graph of Xi, Xc and Z vs. frequency. The graph should include frequencies from 500 Hz to 10 kHz in 500 Hz increments. Your graph should look similar to Figure 17-16 in your text book. This must be done digitally with EXCEL or equivalent graphing software. Locate and label the resonant frequency on your graph. Looking at your graph, approximate the value of the resonant frequency", =

3. Calculate the resonant frequency using Equation 17-4 from Ch. 17 in your text. fr =

4. If the winding resistance of the coil is 0 0 , calculate the precise resonant frequency
(Equation 17-13). fr =

5. Determine the bandwidth.

6. Determine the lower critical frequency and label this point on your graph. fa =

7. Determine the upper critical frequency and label this point on your graph. fcu =

EXTRA CREDIT:

Given the winding resistance in Step 4 of this quiz and a Q.Sk C2 load, draw the parallel equivalent circuit, determine the current in each branch and draw the current phasor.
