I get somewhat annoyed when I hear engineers who have some real-world experience or exposure casually dismiss a component, especially a passive one, as “simple.” It may be simple in concept or ...

Measuring dynamic currents with an oscilloscope is challenging, but this updated differential current probe makes it simple ...

Figure 1: Comparison between conventional and PT-symmetry-based wireless power transfer schemes as the source–receiver resonant coupling rate κ varies as a function of transfer distance d. Figure 3: ...

Although there are several ways to sense current flowing from a source such as a battery, or to a load such as a motor, the current-sense resistor is among the most widely used approaches. There are ...

Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good enough, but sometimes you need better ...

Twelve volts was a big deal when domestic manufacturers adopted it in the '50s. Doubling their voltage from 6 made electrical systems comparatively efficient and the increased power ushered in a new ...

Download this article in PDF format. It’s now common to see circuit boards that carry hundreds of amps, especially in intensive data-processing applications, electric vehicles, and ac distribution.

Proper precision calibration resistors are expensive and usually bulky, often in a large box or can. These are overkill for low-cost handheld digital multimeters (DMMs) and LCR Meters, especially when ...

First, let's define a capacitor: It is an electromechanical device capable of storing electrical energy (electrons). It differs from a battery, as a battery produces electrical energy as a by-product ...
