In the circuit shown below, let






R1=1000;R2=3600;Ri=10000;Ro=600;vt=1;A=5000;

syms vn

vn=solve(vn/R1+vn/Ri+(vn-vt)/R2,vn)

it=(vt-vn)/R2+(vt-A*(0-vn))/Ro

Rout=vt/it;

vn=vpa(vn,11)

it=vpa(it,11)

Rout=vpa(Rout,11)

Answers:

vn =

0.20161290323

it =

1.6819959677

Rout =

0.59453174632

Answer the following statement(s) true (T) or false (F)

1. The product of effective volts and effective amperes is less than the power in watts in any ac circuit having a noninductive resistance load where the current and the voltage are in phase. 2. The dc voltmeter has a d’Arsonval movement, which operates on the same principle as a dc motor. 3. Full-wave rectifiers eliminate one half of the waveform and retain the other. 4. Some manufacturers of dc instruments modify the circuit connections and the scale calibrations to measure ac voltages and currents. 5. The voltage ratings of solid state devices are given as PIV (peak inverse voltage) or PRV (peak reverse voltage).
