You would like a circuit to create a voltage that you can measure that is proportional to your load current. What circuit would you use? There are many circuits to measure current. One common approach ...

Thousands of applications require a circuit to measure a small current. One of the most common is the measurement of photodiode current to infer the light impinging on the diode. Scientific ...

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 ...

If you're seeking a way to measure current and power in a circuit, you need to know about current-sense amplifiers (CSAs). A CSA is a specialized op amp connected as differential amplifier with ...

If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required. A ...

A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

For the PDF version of this article, click here. When designing converters, it is often desirable to measure the dc current coming into the converter. This is particularly true when batteries are ...

Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...

MEASURING live voltages and current in today's high-energy environments can result in a severe hazard to equipment and users if proper precautions are not applied. Given the risk of transients, surges ...
