why are metal prongs of a plug sealed in plastic and rubber
The metal prongs of a plug are sealed in plastic or rubber to provide insulation and protection against electric shock. This covering helps prevent accidental contact with the metal prongs, which carry electricity, making the plug safer to handle and use.
Plastic insulates the prongs from one another, yet is hard enough to keep them at the proper distance to be put into the wall outlet and allow a person to grip the plug.
I think No, plastic is not a better insulator even compared to rubber shoes...Another AnswerYour question is a little like asking, "Is metal a better conductor than a electrolyte?". The reason for this is that there are lots of different types of plastic and various types of rubber. Without knowing exactly which sort of plastic, and what type of rubber, there is no way of knowing which is the better insulator.
Keyboards are typically made from a combination of plastic, metal, and rubber components. The keys themselves are made from plastic, with symbols often printed or engraved on top. The internal mechanisms include metal plates for support and rubber dome switches for key actuation.
The covering of a wire is typically made of materials like plastic (such as PVC), rubber, or nylon. These materials provide insulation and protection for the metal conductor inside the wire.

A plug is typically made from various materials, including plastic, rubber, and metal, depending on its intended use. For electrical plugs, the outer casing is often plastic or rubber for insulation and safety, while the prongs are usually made of metal for conductivity. In plumbing, plugs can be made from materials like rubber, silicone, or metal to create a watertight seal. The choice of material is crucial for ensuring durability and functionality in its specific application.

Three Pronged Sealed BeamThose seald beams which have three metal pins [prongs] have TWO filiments inside; one for the low beam filiment and one for the high beam filiment. The third [center] pin serves as the ground for both filiments.
Mostly metal, sometimes plastic and sometimes rubber+metal or rubber+plastic. Sometimes all 3.
