CHAPTER 6 FILTERS250ANSWERS2.A. XC = 10.6 ohms.B. DC Vout = 10 volts.C. AC Vout = 0.1 volts.D. The DC attenuation is still the same, but the AC output voltage is reduced because of the larger capacitor.INDUCTORS IN AC CIRCUITS28 Figure 6.40 shows a voltage divider circuit using an inductor, rather than a capacitor.VinVoutRLFIGURE 6.40As with previous problems, consider all the inputs to be pure sine waves. Like the capacitor, the inductor cannot change the frequency of a sine wave, but it can reduce the amplitude of the output voltage.The simple circuit, as shown in Figure 6.40, opposes current ﬂow.QUESTIONSA. What is the opposition to current ﬂow called? B. What is the formula for the reactance of the inductor? C. Write out the formula for the opposition to the current ﬂow for this circuit.
