Nodal Analysis Example Problem #1: Two Voltage Sources

This tutorial works through a Nodal Analysis example problem. Nodal Analysis is a method of circuit analysis where we basically just apply Kirchhoff's Current Law (KCL) at each node with an unknown voltage. You can choose to ground any of the nodes, but generally, grounding one with the most branches (especially if they are voltage sources) will make the problem easier. We will end up with one equation per unknown node voltage, and can just solve the system of linear equations to find the branch currents. This example problem features two voltage sources. This video is part of a full free course on electric circuits. The course covers DC circuits, circuit laws, current & voltage sources, series & parallel resistors, nodal analysis, mesh analysis, and AC circuits.
