1. The problem statement, all variables and given/known data Find V1 and i1 using nodal analysis 3. The attempt at a solution I know i1 is 0 because of a circuit break. But, I am not able to figure out how many nodes there are in this circuit? I thought there are four nodes connected to the reference point but the book only considers two. Or is it because we are only looking for V1 so we ignore the other nodes?
