Mesh Analysis - Supermesh

September 27, 2013Resistive CircuitsCurrent Source, Independent Sources, mesh, Power, power calculation, Resistor, Source, supermeshYaz

Solve the circuit and find the power of sources:

$V_S=10V$ , $I_S=4 A$ , $R_1=2 \Omega$ , $R_2=6 \Omega$ , $R_3=1 \Omega$ , $R_4=2 \Omega$ .

Solution:
There are three meshes in the circuit. So, we need to assign three mesh currents. It is better to have all the mesh currents loop in the same direction (usually clockwise) to prevent errors when writing out the equations.
