I have following task
I know it's probably really simple (just simple Ohm's law), but I have no clue what kU is. Could anyone explain it to me in the simplest way possible.
K is a constant that have to be multiplied by U which I guess will be the voltage over R.
The point here is that you don't have to know U value to solve this, I suspect you will be able to get rid of it.
EDIT: Did it myself, you get 2 equation system with 2 unknown parameters U and I. You can solve for both of them.
If kU is a controlled voltage source, then my hint is you can find the node voltages without even knowing that the third element is a resistor, just use KVL by itself. After you know the node voltages, then you can use Ohm's Law to find the resistor current.
