A voltage tester is a tool that senses electrical current when its probes touch bare wires, terminals or placed inside the slots of receptacles. Try to hold both probes with one hand if possible. Some voltage testers can also tell you how many volts are present. A voltage tester often goes by the name voltmeter.
