circuit tester
Voltage detection device
A circuit tester is a device that checks whether electrical current is flowing through a wire or circuit.
The simplest versions are small probes with indicator lights: The circuit tester lit up, confirming the outlet was live.
More sophisticated testers measure voltage, continuity, and other electrical properties.
Essential for electricians and anyone doing electrical work safely.
