Question

The elements in this circuit have the following values: R1=100Ω, R2=100Ω, R3=200Ω, V1=5V, I1=0.01A and I2=0.001A .
please tell the answers for question 1(midterm).and also how to solve them

Answer 1

1) (R*b)/(1+R*b)*vIN
2) (VS*(1+R*b)-vIN)/(1+R*b)
current through R1 =current through R2 =(V1-R3(I1-I2))/(R1+R2+R3)
current through R3 =(V1-(R1R2)(I1-I2))/(R1+R2+R3)
1. Va=(current through R2)*R2+Vb
2. Vb=(current through R3 )*R3
3. power in R1= current through R1*current through R1*R1
4. power in R2=current through R2*current through R2*R2
5. power in R3=current through R3*current through R2*R3
6. power in V1=V1*current through R1
7. power in i1=Vb*current through R3
8. power in i2=-Vb*current through R3

Answer 2

thanks ali... but vb and va aren't comming correct.., can you check this...,

Answer 3

how to get va and vb
