Hi, I have made a thread about electricity a couple of days ago, which Jimmy kindly helped me out with, but I am again, stuck on the last question (most dificult question).
Here is the diagram that I have scanned: http://gallery.cybertarp.com/albums/userpics/12541/electricity2.gif
Basically, I need to find voltage drop across the resistor (V), current flowing through the resistor (I), the resistance constant (R) mainly using this equation: V = IR
I need to find: R1, R2, R3, R4, Rt (total), I1, I2, I3, I4, It (total), V1, V2, V3, V4 and Vt (total).
Well, when I tried to solve this question, I thought because I1 = 8.5A and it is in series with the power source, It = 8.5A also. Then I got stuck. I though I4 is also equal to 8.5A, but apparently, the answer says it's not.
It's quite surprising to see that V2 and V3 have different values. I thought since they are in parallel relationship, they must be the same.
Here are the answers for your convinience:
It = 8.5A
Rt = 4.47ohms
Vt = 38V
I1 = 8.5A
R1 = 2ohms
V1 = 17V
I2 = 3A
R2 = 7ohms
V2 = 21V
I3 = 5.5A
R3 = 2.32ohms
V3 = 12.75V
I4 = 5.5A
R4 = 1.5ohms
V4 = 8.25V
Thank you very much for your help!
