I'v set up the equation for node v1 node, but v2 node confuses me.
would it be correct to assume that the 1A current flows into node 2? Or does only part of it flow into node 2, (with the other part going down the 10 ohm resistor into ground)
How do i find out how much current that 1A source is contributing into node 2.
Also when setting up the KVL for node 1, i have (v1/5ohms) + (v1 - v2)/5ohms... but i can't figure out the current comming through the 10v Voltage source to V1. I coudl do V1-V2, and then divide it by the resistance of the voltage source. but i don't know the resistance of the voltage source.
I'v been at this question for a very long time, and managed to get a whole range of answers from -4 to ~6V. The back of the book says the answer is -3.33V.
How do i do this? I have a feeling i'm missing some fundemental rule with this.
the two equations i got using nodal analysis are:
at V1 I have
(V1/5) + Is -2 = 0
and at V2 i have
Is + 2 + (v2/10) +1 = 0
Please help
