circuit theory

Circuit theory is the study of how electrical current flows through pathways called circuits, which are composed of components like resistors, capacitors, and power sources. It explains how electricity moves, divides, and behaves within these pathways, enabling the design and analysis of electronic devices. Think of it as understanding how water flows through pipes, where voltage is like water pressure, current is the flow rate, and components control or direct that flow. By applying circuit theory, engineers can predict and control how devices operate, ensuring they function safely and efficiently.
