1. The problem statement, all variables and given/known data OK well I have this as a small piece of assessment and Im realy bad at electrical engineering civil is my major heh. http://img161.imageshack.us/img161/2461/image1uw1.jpg [Broken] 1. Find the voltages at A and B (with respect to reference node G) using mesh analysis, 2. Replace subcircuits G-A, A-B, and B-G by their Thevenin equivalents. Hence find the voltages at A and B (with respect to G), the power dissipated in each resistor in the original circuit, and the power supplied by each source. Hint: the power supplied by the current source is about -1.8 watts. 3. Find the voltages at A and B (with respect to G) by using the superposition of the effects of the three sources. 2. Relevant equations KVL, KCL, Mesh analysis, nodal analysis, superposition, thevenin equivelants 3. The attempt at a solution part 1 - I figured that I have to use mesh analysis to find I1, I2 and I3 and then apply the brach currents in R2 and R4 I used mesh analysis and got values for i1/i2 and i3 but dont realy know exactly what to do from there part 2/3 - Im totally lost I realise this is a pretty poor start but electrical engineering is not something ive ever dealt with Any help/guidance is much appreciated if someone wated to give me some realy specific advice my email is email@example.com and my msn is firstname.lastname@example.org Id reimburse you for your time if you helped me out at a normal tutor rate.
