EE 2950 Chapter : Summary Of Techniques
Document Summary
Ee 2950 multiple-source circuit analysis techniques: nodal analysis. Draw in and label branch currents and corresponding resistor polarities. Apply kcl at the labeled nodes (what goes in must come out) Substitute for the currents with ohm"s law. Obtain a set of two simultaneous equations and use cramer"s rule to solve for unknown node voltages. Use the node voltages to find branch currents from ohm"s law. Loop and mesh analysis (caveat: don"t perform kvl in loop/mesh containing a current source) Draw and label mesh currents and corresponding polarities on resistors that have only one mesh current through them. Draw and label net currents (branches containing two mesh currents) and label the corresponding polarities. Write an equation for each net current as a function of the two mesh currents by applying. Perform kvl around loops/meshes (as necessary) to obtain two simultaneous equations. As you perform kvl write the voltages using ohm"s law. Solve the system of equations for the mesh currents.
