We generally don't get electric shocks from electrical appliances because they are designed with safety measures to prevent electrical currents from flowing through our bodies. Here are some reasons why electric shocks are rare:
Insulation: Electrical appliances are designed with insulation materials to prevent the flow of electricity from the internal wiring to the external surface. This insulation acts as a barrier, reducing the risk of electric shock when we touch the appliance.
Grounding: Many appliances, especially those with metal exteriors, are grounded. Grounding provides a path of low resistance for electrical currents, directing them away from the user. If a fault occurs within the appliance and electricity leaks to the metal exterior, the grounding system allows the excess current to safely flow to the ground, preventing the user from getting shocked.
Safety features: Electrical appliances often incorporate safety features like fuses, circuit breakers, and ground fault circuit interrupters (GFCIs). These devices monitor the electrical current and respond by interrupting the flow of electricity if an abnormality or dangerous situation is detected. They help protect against electrical shocks and potential fire hazards.
Regulatory standards: Electrical appliances undergo rigorous testing and certification processes to ensure they meet safety standards set by regulatory authorities. These standards include requirements for insulation, grounding, safety features, and other aspects to minimize the risk of electric shock.
Despite these safety measures, it is still important to exercise caution when using electrical appliances. Avoid using damaged or frayed cords, keep appliances away from water sources, and use them according to the manufacturer's instructions. Regular maintenance, such as checking cords and plugs for wear and tear, can also help ensure the continued safety of electrical appliances.
