What is a power cord called?
A power cord is an electrical component that connects your appliance to the wall outlet. It's made of an insulated electrical cable with one or both ends molded with connectors.
One end is a male connector that goes into the electrical receptacle, wall outlet, or extension cord. The other end has a female connector attached to your appliance or another male connector.
Power cords are used in every kind of electrical appliance—TVs, computers, refrigerators, air conditioners, and more! They're also used in both domestic and commercial settings: you'll find them in homes and businesses alike. And they come in all kinds of sizes: from 16 A to 20 A and 125 V to 250 V respectively.
What is a power cord used for?
A power cord is a cable used to temporarily connect an appliance to the mains through a wall outlet or extension cord.
Power cords are often used with appliances in countries different from those in which they were designed and manufactured. For example, if you have an HP computer purchased in the United States that will have an incompatible power cord when used in another country, it is convenient to have a universal power cord. Even hair dryers purchased in the United States are not compatible for use in Europe; you will find that the numbering and size of 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 is a flexible electrical cable with a plug at one end that plugs into an outlet. They are used to connect electronic devices to an external power source, such as an electrical outlet. The plug contains two or more connectors called pins that fit into matching receptacles in the outlet, and the cable extends from the plug to an electric device.
Consequently, what is inside a power cord?
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, can I power an outlet with an extension cord?
Extension cords are only for temporary use and are not to be left plugged into wall outlets when not being actively used. This plugs into a wall outlet and is considered a power strip even though it doesn't have a cord. Do not plug an extension cord or power strip into it.
How do you plug in a power cord?
Power cords are designed to carry the electrical current from your wall outlets (generally 110v or 240v) to the components you plug in. The power cord consists of a core of metal wire offering good conductivity such as copper or aluminum, along with other material layers including insulation, tapes, screens, armoring for mechanical protection, and sheathing.
These additional layers are designed principally to allow the metal core to continue to conduct electrical current safely in the environment it is installed.
How do you plug in a power cord?
All power cords are not created equal. If a wall-mounted socket or socket on an appliance does not have a three-prong plug, the power cord that connects the appliance to it may not be interchangeable with other appliances with those plugs.
Some three-pronged plugs are unavailable in other countries and some two-pronged plugs are available in both U.S. and Canadian versions (one model of each), but not all countries allow them. Aftermarket adapters may be required in certain cases if the outlet is physically unable to support a particular style of plug.
