How big is the input wire?

This is an old query: How big is a circuit's input wire? Even though it might not seem like much, knowing the answer can be useful when attempting to improve a circuit's efficiency or troubleshoot an existing one. We'll look at how to use basic algebra and physics to figure out the size of an input wire in this article.

The different types of power cords

When looking to buy a new power cord for your electronics, there are a few things to keep in mind. The different types of power cords can be confusing, so we’ll take a look at each one and what they’re used for.

The standard "wall wart" plug is the type of power cord that is used the most. This cord plugs into the wall and is the same length as the majority of electrical outlets. Because they don't use a lot of power, these cords are great for using small appliances like fans and flashlights.

The "extension cord" is another type of power cord. Similar to a wall wart plug, an extension cord has more length so that you can use it to power larger items like computers or TVs. Typically, extension cords are 30 feet long, but they can be longer if necessary.

The "plug-in adapter" is the last type of power cord. A plug-in adapter has its own socket and is a smaller version of a regular plug. If you want to use an appliance that doesn't have a standard plug, this is perfect.

However, just like the power cords you can also check the other materials that will surely helps your needs, materials like Vertical OU rackmount PDU meteringHorizontal  export metering and Managed Rackmount PDU.

The importance of a good power cord

Having a quality power cord is always a good idea, no matter how recent your electronic devices are. A bad power cord will not only make your device work less well, but it could also start fires.

When looking for a power cord, keep the input wire's size in mind. Because they permit more current to flow through them, smaller wires are superior, resulting in faster speeds and longer battery life. Although larger wires can carry more current, they may not supply your device with as much juice.

It's also important to check that the cord is long enough to plug into an outlet and reach all of your devices. Even some cords have indicator lights that let you know when they're plugged in and working properly.


When working with electricity, it's important to make sure the wire you use can handle the amount of current your appliance will draw. In general, carrying a strong current and avoiding unwanted sparks will be easier with a larger wire. If you have any doubts about the size of the wire, double check that it is at least as thick as the insulation in your appliance (typically around 18AWG).
