An electrical circuit is a closed path through which an electric current can flow. It consists of various components, including a power source (such as a battery or generator), wires, and various other components such as resistors, capacitors, inductors, and diodes. Electrical circuits are the foundation of modern electronics and are used in a wide range of applications, from simple light bulbs to complex computer systems.
