Electric circuits

An electric circuit is a closed pathway that allows electrical current to flow, powering devices like lights or computers. It consists of a source of electrical energy (such as a battery or power outlet), conductors (wires), and devices (like bulbs or motors) that use the energy. The circuit must be complete, with no breaks, so current can flow continuously. When the circuit is complete, electrons move through the wires, providing energy to run the devices. If there's a break or switch off, the flow stops, and the devices turn off. Circuits are fundamental to all electronic and electrical systems.
