An LC circuit consists of a 2.91 mH inductor and a 4.97 uF capacitor. (a) Find its impedance at 63.8 Hz. Ω 22 (b) Find its impedance at 11.7 kHz. (c) Now a 35.2 Ω resistor is added in series with the inductor and capacitor. Find the impedance of this RLC circuit at 63.8 Hz and 11.7 kHz. At 63.8 Hz At 11.7 kHz 22 Ω (d) Compare the values of Z in parts (a) and (b) with those found in part (c), in which there was also a resistor. Why are they similar? (Select all that apply.) At low frequency, the capacitor dominates. The resistor makes little contribution to the total impedance. At low frequency, the inductor dominates. At high frequency, the capacitor dominates. At high frequency, the inductor dominates.
