2) Calculate VR in polar (both magnitude and angle) form for the circuits in Figure 10.1, and record the results in Table 10.1A.
Solution
1) f=1000 hz
z=5100+j(2*3.14*1000*200*10^-3-1/(2*3.14*1000*4.7*10^-9))=5100-j32606.11
vr=(5100*2.5<0)/(5100-j32606.11)=0.386<81.11 volts
2) f=2000 hz
z=5100+j(-14418.1) ohms
vr=(5100*2.5<0)/(5100-j14418.1)=0.833<70.5 volts
3) f=3000hz
z=5100+j(3769.911-11287.58) ohms
vr=(5100*2.5<0)/(5100-j7517.669)=1.4035<55.846 volts
4) f=4000 hz
z=5100+j(5026.54-8465.68) ohms
vr=(5100*2.5<0)/(5100-j3439.14)=2.07275<33.99 volts
5) f=5000 hz
z=5100+j(6283.185-6772.55) ohms
vr=(5100*2.5<0)/(5100-j489.365)=2.4885<5.4809 volts.
