Circuit Analysis Series 5: Norton Equivalent Circuit

Circuit analysis is probably the most important Electrical Engineering fundamental course. Many universities require that students take this course to determine who will “make the cut” and continue in the degree program. For anyone interested in joining electrical engineering field, circuit analysis is also the best course to test the waters.
For the example circuit, how much is Va? There are multiple ways to solve this problem. Previously, we used Nodal analysis, mesh analysis, superposition and Thevenin equivalent circuit to solve it.
The fifth Approach is using Norton equivalent circuit. This video explains the steps to solve the problem with this approach, and also explains the key concept of circuit analysis, Norton equivalent circuit.
