When current passes through various objects, different objects have different blocking ability for the passage of current. Some objects can pass the current smoothly, and some objects do not let them pass, or let it pass under a certain resistance. The ability of such different objects to pass current is called the electrical conductivity of such objects. Various objects have different electrical conductivity, and any object with good electrical conductivity is called a conductor. Such as silver, copper, aluminum, lead, tin, iron, mercury, carbon and electrolytes are good conductors. Conversely, an object with poor electrical conductivity is called an insulator. Also, some objects have a lower electrical conductivity than conductors but are stronger than insulators. Such conductors are called semiconductors. Such as the commonly used transistor raw materials silicon, germanium and so on.
