Can you explain what a polarized plug is?

Answer by  JohnHolmes (2660)

A polarized plug is a plug that has different sized prongs which allow them to work only in one direction. They utilize this to keep the current flowing in only one direction, the same as a battery manufactures do with the positive and negative sides of the battery.

A polarized plug is an electrical plug that can only plug into the wall outlet when inserted at the proper orientation. That is, it cannot be plugged in "upside-down." This is due to the fact that one of the prongs is slightly wider than the other; therefore, it will only fit in the proper side of the outlet.
