## Homework Statement

OK well I have this as a small piece of assessment and Im realy bad at electrical engineering civil is my major heh.

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.

## Homework Equations

KVL, KCL, Mesh analysis, nodal analysis, superposition, thevenin equivelants

## 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 protected] and my msn is [email protected] Id reimburse you for your time if you helped me out at a normal tutor rate.
