It is important that electric cords have wires on the inside and a protective outer layer of plastic or rubber for several reasons:
1. Insulation: The inner wires carry electricity from one end of the cord to the other. Without the plastic or rubber outer layer, there would be nothing to insulate the wires and protect them from damage or exposure. This insulation prevents the wires from coming into contact with each other or with other conductive materials, which could result in a short circuit or electrical shock.
2. Protection from physical damage: The outer layer of plastic or rubber also provides protection for the wires from physical damage such as bending, crimping, or abrasions. Without this protective layer, the wires could easily become damaged or severed, leading to a loss of electrical connectivity.
3. Safety: The insulation and protective outer layer of the electric cord help to prevent electric shocks and fires. If the wires were exposed or damaged, there would be a much higher risk of electrical faults that could lead to dangerous situations.
Overall, the combination of wires on the inside and plastic or rubber on the outside ensures the safe and effective transmission of electricity through the cord, protecting both the electrical system and the users of the device or appliance.
