Circuits

Topic

The physics of electric circuits revolves around the principles of how electric charges flow through conductive paths and components. At the core of understanding electric circuits is the concept of an electric current, which is the flow of electric charge, typically carried by moving electrons in a wire. This flow is driven by a difference in electric potential (voltage) between two points in the circuit, provided typically by sources such as batteries or generators.

An electric circuit usually consists of a closed loop or pathway that allows current to circulate. It includes various elements like resistors, which impede the flow of current and dissipate energy as heat; capacitors, which store and release charge; inductors, which store energy in the form of a magnetic field due to current; and other components such as switches, diodes, and transistors, each with specific functions to control or modify the current flow.
