Is the tape conductive?

Ordinary tape does not conduct electricity. 1928 In St. Paul, Minnesota, USA, Richard Drew invented scotch tape. Only by coating a layer of glue on the surface of the adhesive tape can the adhesive tape stick to the object. The earliest adhesives came from animals and plants. In the19th century, rubber was the main component of adhesives. In modern times, various polymers are widely used.

A conductor is an object that is easy to conduct electricity, that is, a material that allows current to pass through, and an object that is not easy to conduct electricity is called an insulator (not an object that can conduct electricity is called a conductor, but an object that cannot conduct electricity is called an insulator, which is a common mistake made by ordinary people). There are free-moving electrons in metal conductors, and the reason for conducting electricity is free electrons. The resistivity of semiconductor decreases gradually with temperature, and the conductivity increases greatly. The reason for conducting electricity is the hole and electron pair in the semiconductor. In science and engineering, ohm is usually used to define the conductivity of materials.
