Question

So I'm really not sure about the loop rule and the various currents. I thought I was, but I keep getting this one wrong so I'll see what you guys think. I attached a picture for reference.

Thanks.

1) Using your results, verify that the junction rule holds true at positions C and F.

2) For each of the circuit loop shown below, verify that the loop rule holds true.

a) Loop A -> B -> C -> F -> A

b) Loop A -> B -> D -> E -> A

c) Loop C -> F -> E -> D -> C

3) Compute the power loss through each of the resistors that are placed in parallel. Which of these resistors uses more power? Briefly explain why this is so.

Explanation / Answer

a) at junction C

I1 = I2 + I3

0.004849 = .002845 + .001988

its ture.

at junction f

same I2+I3 = I1

0.004849 = .002845 + .001988

b) (A) V = Vr1 + Vr3 =4.336.97 = 5.24 V

(B) V = Vr1 + Vr2 =4.336.97 = 5.24 V

(C) Vr2 - Vr3=0

0.97=0.97

3)Pr2 = V*I = 0.97*.002845 = 2.76 mW

Pr3 = (0.97*.001988) = 1.93 mW

R2 uses more power .
