Why do some electical plugs have 2 prongs that are the same size, some have 2 different sizes and some have 3? (US plugs)
Okay, so: Two prongs (blades) are the minimum you need to make an electric circuit: the 'hot' blade and the 'neutral' blade. The 'hot' blade is connected to the house current, and the 'neutral' blade is connected to the return path. If the blades are two different sizes, the plug as a whole is sa…
The Short Answer
Okay, so: Two prongs (blades) are the minimum you need to make an electric circuit: the 'hot' blade and the 'neutral' blade. The 'hot' blade is connected to the house current, and the 'neutral' blade is connected to the return path. If the blades are two different sizes, the plug as a whole is said to be 'polarized;' you can only insert it one way. This prevents the hot and neutral from being swapped. The third, circular blade situated below and between the other two is 'ground.' This is distinct from 'neutral' in that the ground blade is connected to something that's not the electric circuit, so that if something happens and the electric current gets fouled, it dumps to ground rather than dumping through you or through other things, potentially causing a fire.
