Hi all,

I was trying to solve this but I'm stuck as you can see in my notes below:  Using simulator the I1=3.125 A | I2=-1,857 A | I3=4,375 A and Power of the dependent current source = -46.875 W Any idea, what could be wrong ?

Thanks.

In your loop 2 equation you're ignoring the voltage across the current source? So are you pretending it's zero volts?

Thanks.
Since mesh1 and mesh2 share a current source, you must use the super mesh technique, combining mesh1 and mesh2 for your second equation. Have you learned the super mesh technique?
