Circuit

A circuit is a complete, closed pathway through which electrical current flows. It typically consists of a power source (like a battery or plug), wires, and devices such as lights or motors that use the electricity. When the circuit is complete, electricity flows smoothly, powering the devices. If there's a break in the path, the flow stops, and the devices turn off. Circuits can be simple, with just a few components, or complex, like those in computers or appliances. Proper design ensures safe and efficient operation of electrical systems.
