Substances found in nature in which electric charge can move freely from one place to another i.e. conductors are those substances in which charge flow can occur easily. Since charge flows in conductive materials, we can also say that current flows easily in these materials. The silver good conductor but it is not used due to its expensive cost. Substances found in nature in which the charge cannot flow, that is, the current cannot flow through these substances, they are called insulators or conductors or non-conductive materials. These materials are used in places where we do not have to allow the flow of electric current, as the parts of electrical equipment are made of rubber or plastic, here rubber and plastic are anti-electric material because the electric current cannot flow through them.
