See attached file for full problem description.
The circuit shown in Fig. P4.11 is a DC model of a residential power distribution circuit.
a) Use the node-voltage method to find the branch currents i1 --i6.
b) Test your solution for branch currents by showing that the total power dissipated equal to the total power developed.
The solution is comprised of detailed calculations of the branch currents of the residential power distribution circuit by node-voltage method. It also verifies the results by showing that the total power dissipated equal to the total power developed. It can be used a guide on node analysis of the electric circuits by the students.
