La seguridad eléctrica

The video tutorial explains how electric shocks occur and how to protect against them using insulation and creating paths of least resistance. It highlights the use of safety gear like rubber gloves and the role of lightning rods. The tutorial also covers how appliances incorporate insulation and earthing to prevent electric shocks, ensuring safety by providing a direct path to earth and blowing fuses to open circuits.
