But what if I assumed directions(+I1, +I2, -I3 and +I1, -I2, -I3) and in both cases I get different non-negative results?

"Based on your defined currents" How can I find direction of currents? I am understand form of KCL based on direction of currents but I can't understand how to find them. Biggest headeache that absolute value of currents in result depends on third eq. And for me this situation looks like: I need...

Can you pls write it down? Because it's not clear for me. Is it always just I1 + I2 + I3 = 0 or I should at first choose some direction for current and only then use Kirchhoff’s current law based on pre-choosen direction?

So okey. The first two eq are next: E1 - E2 = I1R1 - I2R2 E2 - E3 = I2R2 = I3R3 Or one of them can be replaced by E1 - E3 = I1R1 - I3R3 So what`s the third eq of system? How I can determine it?

But I am already not sure about first 2. E1 - I1R1 + I2R2 - E2 = 0, why I2R2 with plus, does it mean that second resistor create additional voltage and if so how it even possible?

Hi. I have next task: Three current sources with EMF E1 = 11 V, E2 = 4 V and E3 = 6 V and three resistors with resistance R1 = 5 Ohms, R2 = 10 Ohms and R3 = 2 Ohms are connected, as shown on picture below. Determine the current strengths I in the resistors. Internal resistance sources neglect...
