What is a power cord called?
A power cord is an electrical component that connects an appliance to its source of power. It's made from an insulated cable with one or both ends molded with connectors. The male connector goes into the receptacle, wall outlet, or extension cord, while the female connector is attached to the appliance itself. This female connector can be replaced by a fixed wire when necessary.
Power cords are typically used in homes and businesses—you'll see them in every electrical appliance from TVs to refrigerators! Industrial and manufacturing plants rarely use power cords because their equipment draws high amounts of current and requires medium to high voltages. Power cords are limited to current ratings between 16 A and 20 A and voltage ratings between 125 V and 250 V.
What is a power cord used for?
A power cord is a cable that temporarily connects an appliance to the mains through a wall outlet or extension cord.
Power cords are used to connect the devices that require electricity to operate. They help in connecting different devices like computers and mobile phones with their respective chargers. Power cords are also used to connect appliances such as hair dryers, vacuum cleaners, and refrigerators.
Universal power cords and plug adapters are often used with appliances in countries different from those in which they were designed and manufactured. Example. You have an HP computer purchased in the United States that will have an incompatible power cord when used in another country. Therefore, it is convenient to have a universal power cord, especially when almost everyone has important work on the laptop. Even hair dryers purchased in the United States are not compatible for use in Europe. You will find that the numbering and size of the outlets simply do not match.
Products include computer AC power cords and splitters and appliance/indoor/outdoor extension cords.
Amps and watts in power cords
When you're shopping for an appliance cord, you'll see the number of amps and watts on the product page.
Amp is short for ampere, which measures how many electrons can flow through a wire at one time. A higher amp rating means that more electricity can pass through the wire safely.
Watts is another measure of power—this one measures how much work can be done by a current of electricity. So if you have a cord that's 10-amp and 1,250 watts, that means it can carry 10 amps of current (which equates to 1,250 watts) safely.
If you're looking for a replacement appliance cord, we recommend checking both numbers before buying to make sure you get one that will fit your needs. If you need a bigger or longer cord than what came with your appliance originally or want an extension cord to bring power from an outlet in another room closer to where you need it, this is important information to have!
What is inside a power cord?
A power cord consists of a plug, the cordage, and a strain relief connector to secure the cord to the device. The hard-wired power cord consists of a plug, the cordage, and a strain relief device to secure the cord to the equipment enclosure. The detachable power cord, also known as a power cord set consists of a plug, cordage and a connector or receptacle.
Furthermore, you can plug an extension cord into an outlet if it is designed for outdoor use. Do not plug an extension cord or power strip into it. You can buy a power cord for your television if it is still under warranty or replace it yourself if you have some basic electrical skills.
How do you plug in a power cord?
A power cord plugs into an electrical socket and provides a low resistance path for electrical current to flow through. A good conductor is made of a material whose atomic structure has loosely bound electrons in its outer shell, which can move across the atomic matrix of the material (see our FAQ on what electricity is for more information on atoms). This movement of electrons is known as the current flow. On the contrary, good insulators have tightly bound electrons which make it difficult for this current flow.
How do you plug in a power cord?
You can buy a universal power cord that will fit many different electric tools. They do exist, and they are part of the reason why we offer these cords on our website. If the buyer has a powerful tool that uses several types of plugs, but most are US-style at one end, then it is best to buy the right type of cord for this area. It is also possible that certain manufacturers make two- or even three-pronged power cords that only fit their products. In this case, it might be necessary to check with whoever made your product to ensure that he or she recommends using the cord you need by checking old ones first.
