It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

Nickel Cadmium (NiCd) batteries are widely used in consumer electronics due to their high energy density and long life. Constant current charging is often recommended by manufacturers. Several ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...

Forecasters have warned that a former tropical disturbance making its way inland is making Gulf Coast beaches prime for rip currents, a deadly ocean danger that kills dozens every year in the United ...

Planck's constant reveals the quantum world's fundamental energy levels. It shows how light and matter exist in discrete units (quanta). This constant defines limits to our knowledge of particle ...

For years, climate experts have been sounding the alarm about the worsening impacts of global warming, and a report made by a European news wire agency over the weekend heightened the concerns in an ...

Constant currency reporting adjusts revenue and earnings to negate exchange rate effects. Many companies present constant currency data with GAAP results for clearer comparison. Understanding both ...

This year's Atlantic hurricane season officially started June 1, and it could see above-average activity. The National Oceanic and Atmospheric Administration is predicting 13 to 19 named storms by the ...

Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and ...
