- Homework Statement
- How do I know that ##i_x = 0 ~ ?## Is it because of the fact that resistor, source and dependent current source are in parallel? If that is not the reason, what is?

Thanks in advance.

- Relevant Equations
- Norton's theorem

I was first thinking that i_x is zero because the 4 ohms resistor can be ignored because it is parallel with a short circuit, but I assumed that only the resistance is zero whilst i_x flows through and that is what'd make the voltage across 4-ohms resistor to be zero.
