No, electricity cannot pass through thermocol (also known as expanded polystyrene foam). Thermocol is an insulating material, meaning it resists the flow of electrical current. It doesn’t conduct electricity, which is why it's often used as an insulator in various applications like packaging and thermal insulation.
If electricity comes into contact with thermocol, it will not pass through it, but if the voltage is high enough, it could break down the material and potentially cause damage, though this would be rare under normal conditions.
