A plug that has one blade wider than the other is called a ______ plug.

A plug that has one blade wider than the other is called a ______ plug.

• A. Three-prong plug
• B. Polarized plug
• C. Grounded plug
• D. Unpolarized plug

Answer: (B)

Having one blade wider than the other is about safety through polarity. This design makes the plug a polarized one, so the wider blade is the neutral and the narrower blade is the hot. When the plug is inserted correctly into an outlet, the hot side connects to the appliance’s live wiring and the neutral side connects to the return path, which helps reduce the risk of electric shock if you touch exposed parts. A three-prong plug adds a grounding prong and is about providing a safety path to earth, not about blade width. A grounded plug is defined by that third prong. An unpolarized plug has blades of equal width, so there’s no guaranteed orientation of hot versus neutral.
