The path that electricity takes is called a circuit. In simple terms, a circuit is a closed loop that allows electric current to flow from a power source, through various components, and back to the source.
A circuit typically consists of a source of voltage, such as a battery or an outlet, conducting pathways like wires, and loads that use electricity, such as light bulbs or motors. When the circuit is closed, the electricity flows uninterruptedly, powering the connected devices. If there’s a break anywhere in the circuit, the flow of electricity stops, and the devices do not operate.
Understanding circuits is fundamental to electronics and electrical engineering, as it helps in designing and troubleshooting electrical systems.
