DC Circuit Analysis is the study of electrical circuits that operate with direct current (DC), where the flow of electric charge is constant and unidirectional. This analysis involves understanding how voltage, current, and resistance interact within a circuit, often using Ohm's Law, which states that voltage equals current times resistance (V = IR). In DC Circuit Analysis, various techniques such as mesh analysis and nodal analysis are employed to solve for unknown values in a circuit. These methods help engineers design and troubleshoot circuits in applications ranging from simple battery-powered devices to complex electronic systems.
