HI,
1. The problem statement, all variables and given/known data
I have a closed circuit, with 7 bulbs, all of unequal resistances. I know three currents, 300, 200 and 500. I have 4 unknown currents, those fllowing through A, b, C and D which I need to find.
There is a graphic for this which I don't know how to insert, but the link to go to it is:
**broken link removed**
GO to the link, scroll to page 123, and the diagram is problem 17.
2. Relevant equations
Loop rule where sum voltages in a closed loop = 0
Junction rule where the sum of currents flowing into and out of a point=0.
3. The attempt at a solution
I started by labelling the known currrents, from the left, G E and F, giving me a name for each one.
I know I need to use the junction rule to calculate the currents and I have this:
Rg+Re+Rf = Ra+Rb+Rc+Rd
1000= Ra+Rb+Rc+Rd
Can anyone help me?
