Why are electrical plug prongs different sizes? It is a minor safety enhancement. Since the 1950’s power outlets in the US are made with one slot wider than the other. This means the plug can only fit in the socket one way, with the wide blade in the wide slot. The wide slot is supposed to be connected to neutral (which is tied to ground) and has zero volts.
Why is one plug prong bigger than the other? Polarized nongrounding-type plugs have one prong, the neutral, that’s larger than the other to ensure that the hot wire, which is the smaller one, is tapped correctly. Electricity streams in a circuit, which is a closed path of components where electrons flow from a current source.
Why are plugs shaped differently? At first, plugs in the U.S. had only two tabs without a ground pin. Engineers developed the idea of a ground pin to make plugs safer in the 1920s. … So because different countries adopted innovations like these at different times, the plugs that they used changed throughout the years.
Why are there two different flat prongs on an electric plug? Many plugs have only two prongs. On two-prong plugs, there is no ground wire connection, as it’s deemed unnecessary. In these plugs, one of the blades of the plugs connects to the neutral wires running through the appliance, while the other blade connects to the “hot” wires.
