A power cord is an electrical cable that connects an appliance or device to a power source, such as a wall outlet. It typically consists of two or more insulated wires that carry electricity, along with a plug at one end and a connector at the other. Power cords are essential for providing the necessary energy to operate various devices, including computers, televisions, and kitchen appliances. Power cords come in different types and lengths, depending on the device's requirements and the electrical standards of a region. They may also include safety features, such as fuses or circuit breakers, to prevent overheating or electrical hazards. Proper handling and maintenance of power cords are important to ensure safety and functionality.
