Designed for EVs and HEVs, these current sensors deliver accurate, isolated measurement for batteries, motors, and safety ...

Makers, developers, and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published on the official Arduino blog. This project ...

Common traits of digital multimeters (DMMs). Classifying DMMs by their amount of digits. What role do digitizers play in making voltage measurements? Measuring voltage may be the most basic ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

Texas Instruments tells us that Battery-monitoring systems are used to estimate state of health (SOH) and state of charge (SOC), especially in Electric Vehicles (EVs). To get detailed information ...

Current sensing is used to perform two essential circuit functions. First, it is used to measure “how much” current is flowing in a circuit, which may be used to make decisions about turning off ...

A farmer is watering an alfalfa field 24 hours a day using a 3-phase 100-hp electric motor and adjustable speed drive (ASD). The farmer checks on his field to find the water not flowing and the pump ...

Measurement triangle: this quantum metrology triangle shows the relations between the three electrical units volt, ohm and ampere and the involved fundamental constants. Researchers at PTB are ...

When you measure a voltage, how do you know that your measurement is correct? Because your multimeter says so, of course! But how can you trust your multimeter to give the right reading? Calibration ...

Next is the H-bridge, which resembles an H (Figure 2), which is used typically with a brushed DC motor. In addition to run, coast, and break operating modes, it can also reverse a motor. Simplified ...

What do a Rogowski coil, a magnetic core, and a hall effect sensor have in common? They are all ways you can make oscilloscope probes that measure current. If you think of a scope as a voltage ...

Historically, researchers impaled giant squid, snail, and frog axons with electrodes to study nerve function by measuring ion channels. Today, electrophysiologists have enhanced their ability to ...
