An LC circuit consists of a 2.87 mH inductor and a 4.85 μF capacitor.
(a) Find its impedance at 56.1 Hz.
(b) Find its impedance at 12.0 kHz.
(c) Now a 35.2Ω resistor is added in series with the inductor and capacitor. Find the impedance of this RLC circuit at 56.1 Hz and 12.0 kHz.
(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 high frequency, the capacitor dominates.At low frequency, the capacitor dominates.At low frequency, the inductor dominates.The resistor makes little contribution to the total impedance.At high frequency, the inductor dominates.
