While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when it came time to sense the current ...

As the primary switching device used in a broad range of power conversion applications, MOSFETs play a central role in power supply design. Defining their performance characteristics is crucial to ...

Sponsored by Texas Instruments: Often used for overcurrent protection, current-sense amplifiers are now finding homes in a wide array of applications, including automotive electronic fuses and ...

To measure a zener diode’s breakdown voltage, you need a dc voltage source whose voltage exceeds that of the zener voltage. In Figure 1, resistor R SER provides voltage drop between V IN and V ZEN. In ...

The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens.
