No, electric current cannot pass through a sheet of thermocol. Thermocol, also known as expanded polystyrene foam, is an **insulator**, meaning it does not allow the flow of electric current. It is a poor conductor of electricity because its molecular structure does not have free-moving electrons, which are necessary for the flow of current.
So, if you try to pass an electric current through thermocol, it will not conduct the electricity. Instead, it will block the current, which is why thermocol is often used for insulation purposes in electrical applications.
