Here's an overview some of the major electrical issues to watch out for and learn how to prevent them from happening.

One characteristic of adding PV solar to homes is a massive increase in high-voltage and high-current DC installations. With this comes a need for suitable breakers, but without the requisite ...

In a metal like copper, however, the outer electrons swim around freely and are shared by all the atoms. That’s why ...

Before a spectrometer can do any useful work, it needs to be calibrated to identify wavelengths correctly. This is usually done by detecting several characteristic peaks or dips in a well-known ...

We've done the testing, and Apple's latest iPhone chips have the horsepower for a capable, low-cost MacBook laptop running on purely smartphone silicon. Might Apple make it happen? From the laptops on ...

Never plug a space heater into a power strip. The high wattage can overload it and cause a fire. Always plug heaters directly into a wall outlet for safety.
