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).
Electrons are negatively charged, so they will be attracted to the positive end of a battery and repelled by the negative end. When the battery is hooked up to a device that lets the electrons flow through it, they flow from negative (anode) to positive (cathode) terminal.
