Homework Statement
Find the potential difference ##V_A– V_B## for the circuit shown in the figure.
Homework Equations
Kirchhoff's laws.
The Attempt at a Solution
If we assign potentials to junctions starting by setting ##A=0## Current ##i_1## flow through each vertical resistances and ##i_2 ## through slant resistances. B has potential ##i_1+2## and there exist a relation ## 1+i_2+i_1=0## between ##i_1## and ##i_2##. I need one more equation. In which loop should I apply KVL. Is there a better way to approach this ?
