A polarized plug is designed to ensure that the electrical current flows in a specific direction, which enhances safety by reducing the risk of electrical shock. The key characteristic of a polarized plug is that its prongs are of different widths. This design allows the plug to be inserted into an outlet in only one way, aligning the larger prong with the wider slot in the outlet, which is typically connected to the neutral wire.

This unique feature helps to differentiate the hot wire from the neutral wire when the device is plugged in, ensuring that any switches or internal components are aligned correctly. This makes it harder to accidentally reverse the connection, which could lead to dangerous situations.

The other characteristics mentioned do not directly indicate polarization: a third prong generally refers to a grounding feature, voltage markings pertain to the electrical specifications rather than polarity, and the material of the plug does not determine its polarized status.
