Answer 1

Answer #1

I we write Kirchoff's rules for the meshes 1 and 2 and for the junction c we get:

Since we want to solve for i₂ and i₃ we can rewrite the equation for the second mesh as:

Now we have to solve the following equation system:

Note that if we divide the second equation by -2 then we can add them and solve for i₂

Adding both equations:

Replacing backwards we can solve for i₁
