Nodal Analysis

Nodal analysis is a method used to determine the voltage at various points (nodes) in an electrical circuit. By applying fundamental principles like Ohm's Law and Kirchhoff's Current Law, it sets up equations for each node, relating unknown voltages to known sources and resistances. Solving these equations provides the voltage at each node relative to a common reference point, enabling engineers to understand how the circuit distributes electrical energy. It’s a systematic approach that simplifies analyzing complex circuits, especially those with multiple components and interconnected paths.
