DC Network theorems Norton’s and Thevenin’s theorem

[steven1988]

hi,
thanks for taking time to try and help me out, i have hit a brick wall with these questions, i have made an attempt and don't no where to go from there, and feed back would be great thanks alot...

The problem
Using both Norton’s and Thevenin’s theorem determine the power dissipated in the 4Ω resistance.

If the 4Ω resistance was removed calculate the value of load that will result in maximum power being transferred

Calculate the value of power transferred

the circuit has a:-
60 V supply
10Ω
10Ω
20Ω
5Ω
5Ω
4Ω
2Ω
1.5Ω
1Ω

Homework Equations

I = V
Z
P= I^2R

The Attempt at a Solution

I = V
Z
= 60
58.5
= 1.02
P= I^2R
= 1.02^2 * 4
= 4.426 W
I = V
Z
= 60
54.5
1.10
P= I^2R
= 1.10^2 * 54.5
= 65.945 w
