### How can you tell what is the net direction of current flow when there are two opposing sources?

How do you tell whether the 12V source will overpower the 5A source at the 4ohms resistor? Changing the net current direction in Node V2. Or vice versa, if the 5A source is stronger than the 12 V.

### Nodal question with current-controlled voltage source connected to independent voltage source

so i've got a question here the question is to calculate v1 & iΦ, of course for nodal analysis (v1/24) + ((v1-(60+6iΦ))/3) + ((v1-va)/2) = 0, but (with va as the node left of 2 ohm resistor) how ...
