1. The problem statement, all variables and given/known data I need to find voltages and currents in the following circuit, using Kirchoff laws. The purpose is not to gain knowledge in electricity, but to write a program that solves a system of equations using Gauss elimination method. I think I wrote correct program, but I also need to get correct equations. Supervisor advised to draw the circuit in simpler fashion to find the voltages, and only then use Kirchoff laws, so that I can be sure I have found right equations that give right values. However, I'm kind of lost in this electricity stuff and since that is not the point of the exercise at all, I'm looking for some help. 2. Relevant equations 3. The attempt at a solution I thought that maybe resistor 25 is in parallel with 23, 34 and 45, and 12 and 56 are in series with this part of the circuit. And that the voltage over the whole circuit is 200 V. It gave me following values: U_25 = 123.07692307692308 U_56 = 46.15384615384616 I = 30.76923076923077 U_12 = 1.5384615384615385 I1 = 4.615384615384616 I2 = 6.153846153846154 Are these correct?
