Circuit Tester

A circuit tester is a device used to determine the presence or absence of an electrical current in a circuit. It is designed to verify whether electricity can flow through a specific point in the circuit and helps identify issues such as open circuits, short circuits, or faulty components. Typically, a circuit tester consists of a probe or a set of probes that are applied to different points in the circuit, providing visual or audible indications of the electrical status. This tool is widely used by electricians, technicians, and DIY enthusiasts to troubleshoot electrical systems and ensure proper functionality.
