Continuity Tester. A continuity tester can be made from a flashlight bulb, flashlight battery, and three
pieces of wire (figure B-2). When the free ends of the wires are touched to a circuit where continuity (or a short) exists,
the bulb will glow. If a two-cell flashlight bulb is used with only one battery, the bulb will glow with one-half its normal
brilliance.
