In the circuit shown below, let
Vs=5;
R1=3000;R2=2000;R3=5000;R4=1000;gm=0.0005;
syms V1 V2
[V1,V2]=solve((V1-Vs)/R2+V1/R3+gm*V1,...
(V2-Vs)/R1-gm*V1+V2/R4,V1,V2)
IR4=V2/R4
PR4=V2*IR4
V1=vpa(V1,7)
V2=vpa(V2,7)
5
IR4=vpa(IR4,7)
PR4=vpa(PR4,7)
Answers:
V1 =
2.083333
V2 =
2.03125
IR4 =
0.00203125
PR4 =
0.004125977
