Electronic paper has two key characteristics that set it apart from other displays: it is bistable, meaning it retains a static image even without electricity, and it is reflective, reflecting ambient light rather than emitting its own. Because of these properties, electronic paper is highly energy...
Electricity is a force caused by electric charge. It is a form of energy which we use to power machines and electrical devices. Click for more Electricity worksheets and facts in PDF and Google Slides format!
Sodium is most often found outside the cell, in the plasma (the non-cell part) of the bloodstream. It is a significant part of water regulation in the body, since water goes where the sodium goes. If there is too much sodium in the body, perhaps due to high salt intake in the diet...
Wireless charging technology has been around for more than 100 years, but its inclusion in devices such as Apple's new iPhone line has given it new life. Here's how it works, and why it could soon show up in everything from homes to robots.
Its stalls can deliver up to 200 kilowatts and come with built-in battery storage, allowing for lower electricity rates and the ability to remain operational even when power grids go down. If that sounds like it could very well rival Tesla’s SuperCharger network, it’s no coincidence: Quin...
Fundamentals of 3-Phase Electricity | What Is 3-Phase Power?, Part 1 From the series: What Is 3-Phase Power? In AC electrical systems, 3-phase power is commonly used due to the increased power density, efficiency, and operational flexibility compared with single...
So how can we visualize electricity moving through a circuit? Well, we can see the water moving, so let’s use it as an analogy to explain how electrical circuits work. It is a well-known fact that if the water is to flow out of a pipe, the water needs to have a force or “pre...
(For an example of coronal discharge, look to aviation. So-called "static wicks" on airplanes are used to prevent too much static electricity from building up on the body of the plane—because if it does, it tends to discharge itself at places vulnerable to coronal discharge, such as edges...
Because electricity is ordinarily invisible to the naked eye, someone who intends to work as an electrical engineer should be curious about mysterious forces that significantly affect the universe but aren't obvious to a layperson. A future electrical engineer should have a powerful...
Monocrystalline silicon is used in the photovoltaic cells that some solar panels use to convert sunlight into electricity. Another form, amorphous silicon, is used to make the glass that covers solar panels, but it has also found its own use in thin-film solar cells. This type of silicon has...
