Answer Exercise 6.2.4 if, instead of the current source, you put a 1.5 volt battery on wire 1.
Exercise 6.2.4
(a) Write down the incidence matrix A for the illustrated electrical network.

(b) Suppose all the wires contain unit resistors, except for R4 = 2. Let there be a unit current source at node 1, and assume node 5 is grounded. Find the voltage potentials at the nodes and the currents through the wires.
(c) Which wire would shock you the most?
