## Homework Statement

Hey guys,

I have been struggling on this problem for a while now and was hoping I could get a little help

What is wanted is the maximum value of Ro for maximum power.

## Homework Equations

## The Attempt at a Solution

Knowing that the Maximum power transfer to Ro would be when Rth=Ro, I am just looking for a Thevenin equivalent.

I have gone through and did the Rth to be equal to 2.5k omhs.

I did Mesh Analysis and got the following 2 equations and 1 controlling equation:

2400(i1)+60+4800(i1-i2)=0

4800(i2-i1)+1800(i3)+1600(i3)=0

(i3)+(i2)=.015Amps

[/B]

Which I reduce to:

7200(i1)-4800(i2)=-60

-4800(i1)+4800(i2)+3400(i3)=0

(i3)=.015-(i2)

Knowing that I want to get the (i3) which would tell me the current going through the Thevenin equivalent. I have also used Current Node Analysis and would want to find the Voltage drop through the 5k resistor. The answers supplied should be 4V and .0016Amps.

Any help would be great, Thanks.
