# Nodal Analysis Question

I however do not see any wrong with my approach. But I am not getting the correct answer. Is there anything to do with grounding? Or am I missing something else?

• How did you get an amperage for $V_B$? That's definitely wrong. I haven't looked through the rest yet to see what else is wrong. Jan 25, 2016 at 20:01
• @helloworld922 I didn't get you. Will you please elaborate? Jan 25, 2016 at 20:04
• In the very last line, you have $V_B = -49.37 A$. Jan 25, 2016 at 20:06
• In your first equation for node B, you have $I_3 + I_4 + I_5 = 0$ but your diagram shows $I_3$ flowing in to node B, while the other currents flow out. So that is a sign error. Jan 25, 2016 at 20:23

where $I_1$, $I_2$, and $I_3$ are all leaving the node (consistent with the arrows in your diagram). However, then you immediately define
