1. The problem statement, all variables and given/known data In attatchment 2. Relevant equations Not sure How to come up with the other equations. 3. The attempt at a solution Assuming a node is an element connected to two or more elements. 1) Moving clockwise from V i1 to i2. Node one is between the negative side of the voltage source and first resistor. 2) Node 2 is from first resistor to second resistor on the right and 3rd resistor down the middle. 3) Node 3 is the top right hand corner between those two resistors. 4) node 4 is the entire wire running down from the far right resistor and middle resistor and to the voltage supply. I also have two loops. Loop A encompass i2 i7 and i6 and loop B encompasses i3 i4 i5 and the middle resistor. I'm having trouble setting up the equations as all the references i've looked at have done the questions a little different. Mainly just using the junction method. current entering = current out. I have no experience on circuits so this is just what I make of the information I've read. eq 1 ) using node 1. i1 - i2 = 0 eq 2) using node 2. i2 - i3 - i7 = 0 eq 3) using node 3. i3 - i4 = 0 eq 4) using node 4 i5 + i7 - i6 = 0 eq 5) loop a i2*R + i7*R - V = 0 eq 6) loop b i3*R + i4*R - i7*R = 0 this is where i'm stuck and i'm unsure about my above equations. Is there a outside loop around the entire circuit or is there a node i have missed. I assume i need 7 equations for the 7 unknowns. Any help would be much appreciated. Kind regards.
