HPHY 253 Homework 33bAlternating-Current CircuitsDr. A. E. BakName1. Serway & Jewett Problem33:21. ARLCcircuit consists of a150-°resistor, a21:0-°Fcapacitor, anda460-mHinductor connected in series with a120V,60:0-Hzpower supply.(a) What is the phase angle between the current and the applied voltage?(b) Which reaches its maximum earlier: the current or the voltage?2. Serway & Jewett Problem33:24. An AC source with±Vmax= 150Vandf= 50:0Hzis connectedbetween pointsaanddin FigureP33:24.(a) Calculate the maximum voltage between pointsaandb.(b) Calculate the maximum voltage between pointsbandc.(c) Calculate the maximum voltage between pointscandd.(d) Calculate the maximum voltage between pointsbandd.3. Serway & Jewett Problem33:46. Consider the °lter circuit shown in Active Figure33:23a.(a) Show that±Vmaxout±Vmaxin=1=(!C)qR2+°1!C±2is the gain ratio, that is, the ratio of output to input voltage amplitudes.(b) What value does the gain ratio approach as the frequency decreases toward zero?What valuedoes the gain ratio approach as the frequency increases without limit?(c) At what frequency is the gain ratio equal to one-half?
