Why is a 3 prong plug safer than a 2 prong plug?

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. Hence 3-pin plugs are safer as compared to 2-pin plugs. Hope this helps.
