How to Determine the Hot Cable An alternating current (AC) setting is often labeled with a V and a squiggly line or initials like ACV. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Use a multimeter to measure alternating current (AC) or direct current (DC). After first removing the lightbulb, screw the adapter into the light socket. Place the black probe on the negative terminal, ground, or neutral wire. A full-size multimeter might be overkill for homeowners, but they can tell an electrician a lot about an outlet, switch, fixture, or circuit. The meter should indicate continuity. They are generally more expensive than the basic testers but still not too pricey. The symbol for direct current (DC) is a V with 3 dots or a dash above it.
