The Superposition theorem is a fundamental principle used in linear electrical circuits that states the response (voltage or current) in any branch of a bilateral linear circuit having more than one independent source equals the algebraic sum of the responses caused by each independent source acting alone. This theorem simplifies the analysis of complex circuits by allowing the consideration of one source at a time while all other sources are replaced by their internal impedances.

linear electrical circuits

Voltage, also known as electric potential difference, is the measure of potential energy per unit charge between two points in an electric field. It is the driving force that pushes electric charge through a circuit, enabling the flow of current and the operation of electrical devices.

voltage

In physics, 'current' refers to the flow of electric charge, typically measured in amperes, and is a fundamental aspect of electrical circuits that influences how devices operate. Current can be direct (DC) or alternating (AC), each with distinct characteristics and applications in technology and power systems.
