You notice an electrical wire is hanging from the ceiling in the basement. The owner says it has always been like that and believes it is not connected to anything. You determine if the wire is live by using a voltage detector. Also known as a voltage "sniffer" or tester, this tool can detect if a wire is hot. If there is voltage being sent through the wire, the detector will light up in reaction to the voltage present in the electrical wire.
