Question: what is the difference between 2 pin and 3 pin plug?
Answer: The 2-pin plug consists of two prongs, one called the 'hot' or 'live' and the other called the 'neutral'. When connected with an electric circuit, the current flows from the live to the neutral prongs. ... 3-pin plugs also limit the amount of power that can flow through the circuit, as compared to a 2-pin plug.
