DC Circuits Techniques. Nodal Analysis for DC circuits By the end of the session, students should be able to: • Solve complex DC circuits using Nodal Analysis • Apply KCL in more complex circuits Solving more complex DC circuits with more than 1 node requires the application of Kirchhoff’s current law at each node. Care must be taken when applying KCL. • The algebraic sum of all currents around a circuit node is equal to zero. Basic circuit analysis has been introduced in class. Attempt all questions using nodal analysis
