Key Concepts

Closed Circuit

A closed circuit is an electrical circuit that forms a complete path for current flow. For any electrical device—such as a bulb—to operate, the battery, wires, and load must be connected in a way that allows electrons to travel in a loop from the battery's negative terminal, through the device, and back to the battery's positive terminal.

Open Circuit

An open circuit is one where the path for electrical current is broken or incomplete, which prevents any meaningful current flow. If the circuit is not fully connected, even though all components are present, the current will not circulate, and devices such as bulbs will not light.

Role of Components in a Circuit

Every component in an electrical circuit has a specific function. The battery provides the electrical energy (voltage) needed to drive the current, the bulb acts as a device that converts electrical energy into light (and some heat), and the wires serve as conductors that link all parts of the circuit. Their proper arrangement ensures that a continuous path is established for current flow.
