Answer :
Final answer:
Double-insulated devices utilize extra insulation to enhance safety and eliminate the need for grounding.
Explanation:
The concept of double-insulated devices
Double-insulated devices are designed with two layers of insulating material to provide an extra layer of safety, reducing the risk of electric shock. These devices are predominantly made of plastic, a nonconductor, making them safe to use in various environments where grounding may not be feasible. The additional insulation in double-insulated devices ensures that they do not need to be grounded, as the second layer of insulation acts as a safeguard against electrical hazards.
