Homework Statement
Use the node-voltage method to find v0 in the circuit below.
Homework Equations
i1+i2+...in=0
i=v/R
The Attempt at a Solution
So I set my reference node to the top of the middle line(above 25Ω)
Equation...
24V/(20+80)Ω+v0/25+.004A=0
Now I can solve for v0=(-.004-24/100 )* 25, v0=-6.1V
I think I did something wrong, I'm confused about a few things. How do I know where to take my reference node? Also, I'm solving for v0, yet I'm adding .004 amps to the answer. Since I'm solving for voltage, how is this possible?
