Which Side of a Battery is Positive? A cell or battery is drawn with a long line and a shorter line. The long line is the positive side (plus is longer). The short line is the negative side (minus is shorter).
This should be the positive side of the battery. When you touch the wire to the surface of your battery, it should light up. This is because the electrons flow out of the negative terminal of your battery, through the bulb, and back into the positive side.
