1. The problem statement, all variables and given/known data ive tried many things and cant seem to grasp the concept of KCL.i know the node im looking for is between r1 & r3. i assumed i1+i2=i3. also looking for directions of currents. V1=30v V2=40v R1=82 R2=68 R3=47 Vx = ? 2. Relevant equations i1 + i2 + i3 = 0 ? 3. The attempt at a solution (30-Vx)/82 + (Vx-40)/68 = Vx/147 anyone help me out with KCL and Nodal analysis? ive been trying for awhile and cant seem to wrap my head around it.
