I have no idea what I a doing. I dont know how to deal with the two symbols (the one that looks like a diamond and a circle with an arrow). If those were replaced with a battery I would be able to solve it, but I can't solve it because I dont know which direction the current is flowing in each branch of the circuit. Anyways I did KVL for each loop and can someone tell me if I am correct? Loop 1: I0(6kΩ) - Vx + i1(8Ω) = 0 Loop 2: Vvoltage over element of 5A - i1(8Ω) + Vx = 0 Loop3: -3Vx - Vx = 0 Out most loop: i0 - 3Vx = 0 Can someone let me know if that is correct? Then what should I do next to solve for i0?
