I have this circuit which I have to solve for Io using nodal analysis. Everything seems easy but I am confused about the nodal equation for V2 given below in the solution. They seemed to ignore the part of the node that goes from V2 to ground, through the 2 1-ohm resistors? In other words, shouldn't there be another term that looks like: $$\frac {V_2}{2}$$

Can you please clarify this? Thank you.

• The only components connected to V2 are R3, the capacitor, and the 4A current source. Apr 11 '15 at 0:40
