## Homework Statement

Determine the norton equivalent Circuit

## Homework Equations

Norton theorem

## The Attempt at a Solution

First, I transform 5A and 10 ohm (in parallel) into 50 V and 10 ohm in series

So, there are three meshes,

for Mesh 1 (I assume the current is clockwise)

##30 i_1 - 10 i_2 = -20##

for Mesh 2

##40 i_2 - 20 i_3 = 50##

for Mesh 3

##40 i_3 - 20 i_2 = 20##Solving those three equations, I get ##i_1 = 0 A##, ##i_2 = 2 A##, ##i_3 = 1.5 A##

So, I_norton is i1 + i2 - i3 = 0 + 2 - 1.5 = 0.5 A

But, this is wrong answer. Please tell me where I got this wrong.
