Product description

Substances that are not good at conducting current are called insulators, which are also known as dielectrics. Their resistivity is extremely high. Definition of insulator: An object that is not easily conductive is called an insulator. There is no absolute boundary between insulators and conductors. Insulators can be transformed into conductors under certain conditions. Note here: The reason for conductivity is that whether it is a solid or a liquid, if there are electrons or ions that can move freely inside, then it can conduct electricity. Without freely moving charges, under certain conditions, conductive particles can be generated, which can also become conductors
