Nodal Analysis 4) Solve the resulting system of linear equations. Nodal Analysis 4) Solve the resulting system of linear equations. Nodal Analysis 4) Solve the resulting system of linear equations. Nodal Analysis What if there are dependent sources? Nodal Analysis What if there are voltage sources? Nodal Analysis What if there are voltage sources? Nodal Analysis Mesh(Loop) Analysis 1) Identifying the Meshes Mesh: A special kind of loop that doesn’t contain any loops within it. Mesh(Loop) Analysis 2) Assigning Mesh Currents 3) Apply KVL around each loop to get an equation in terms of the loop currents. For Mesh 1: For Mesh 2: Mesh(Loop) Analysis 3) Apply KVL around each loop to get an equation in terms of the loop currents. 4) Solve the resulting system of linear equations.
