Amperage measures the rate that current flows through an electrical circuit. If voltage is like water pressure, amperage is ...

Did you know that 1 horsepower is the amount of power required to lift 550 pounds to a height of 1 foot in 1 second? Or, did you know that a foot-pound of torque is literally 1 pound of force exerted ...

Both watts (W) and volt-amperes (VA) are units of measurement for electrical power. Watts refer to “real power,” while volt-amperes refer to “apparent power.” Usually, electronic products show one or ...

In this week’s Gizmodo University: Discover Electronics, we’re diving headfirst into the principle theories of electronics. The second of four classes in this series, “Volts, Amps, and Ohms” is ...

Analog topologies abound for converting current to voltage, voltage to current, voltage to frequency, and frequency to voltage, among other conversions. Figure 1 joins the flock while singing a ...

Editor’s note: This article is part of our roundup of USB-C battery packs. The simplest way to discuss electrical power is in units of volts (V), current measured in amperes or amps (A), and watts (W) ...

Measuring a voltage is pretty easy: just place your multimeter’s probes across the relevant pins and read the value. Probing currents is a bit trickier, since you need to open up the circuit and place ...

If you’re shopping for your first ebike or electric scooter, you might be a bit confused by the numbers you see on the spec sheet. What exactly is a watt-hour (Wh), and how is it different from an amp ...

Because of the shell arrangements of electrons in various atoms and molecules, some substances are quite good at allowing a few electrons to move about freely (e.g., copper, silver, gold, aluminum), ...
