What does it mean if a power cord is polarized?

The system of hot and neutral wiring is what is meant when we speak of a house's electrical system as being "polarized." It simply means that there are both neutral and hot wires and that there is a directional flow to how the current runs through the system.

Does it matter which way you plug in a non polarized plug?

So although flipping the plug around and inserting it backwards will probably be no problem with regard to the electrical operation of the appliance, it may create a safety hazard by exposing the "hot" half of the outlet, the half not connected to Earth, such that someone might touch it and be shocked.
