Run your fingers along the wire to determine which side has the ribbing. Improperly connecting a device to a power source could cause an electric shock or even a fire. In other words, for one reason or another, the white wire is hot rather than neutral, and the black wire is neutral instead of hot. The neutral wire completes the circuit by transferring current away from the appliance. It is usually the shorter of the two prongs, and is designed to connect to the negative side of the circuit. Grounded (neutral) goes to the threaded shell of the lamp and is wired direct without break to the wide blade of a polarized 2 prong plug or in the case of a suspended lamp, to the grounded (neutral) white wire. In this way, is the big prong on a plug positive? Probably because it is safer. Reversed polarity creates a situation where the socket sleeve is hot.
