because
1) Very Low Resistivity 15.9 nΩ m.
2) Silver and Gold are the only metals, being found in a pure form from the earth.
3) silver is a good conductor of electricity like many other metals because the atoms that make up a piece of silver will have many free electrons that can be moved by applying voltage across it. These moving electrons are known as an electric current and they are necessary for making electrical and electronic equipment work correctly.
