You have two meshes. That means you have two mesh equations. What did you do with the second equation?

Hi,

Real quick, i dont see the 6 ohm resistor as being entered into any of the equations.

I was taught that when using Mesh-Current Method, all the mesh currents should be rotating in the same direction. This simplifies the analysis.

You claim to have solved for i(t) after doing just one loop equation. What happened to i2? In the next loop equation you claim that i2 = 0. What is that claim based on?

Hi again,

Yeah i was wondering that too

My advice for him based on his replies and attempts would be to try to solve a SINGLE loop circuit first, then move on to a two loop circuit. Get that right first, then move on to a more complicated circuit.

NOTE to the OP:
Typically for a two loop circuit you would have two currents to solve for i1 and i2, so you would have two equations, and you would solve those two equations simultaneously for i1 and i2 and then go from there.
