1. The problem statement, all variables and given/known data From the attached file using Kirchoff's laws prove that V AB = V AD and that i1 = i/2 2. Relevant equations V1 + V2 + V3 +... Vn = 0 (The sum of the voltage applied and dropped across the components is zero. i1 + i2 = i3 (The sum of the branch currents is equal to the total current) 3. The attempt at a solution I thought I was ok with algebraic manipulation but this has stumped me :-( any pointers would be appreciated as always!
