Temperature is by far the most commonly measured physical parameter. With so many new ideas for connected devices in the works for consumer and industrial applications, you often need high-accuracy ...

Current measurement components and methods must provide an accurate output signal as well as preventing damage to the associated printed circuit board. Current sensing is used to perform two essential ...

An ammeter is always connected in series with the component whose current you want to measure. This means it is placed ...

This application note describes the use of current-sense amplifiers, differential amplifiers, and instrumentation amplifiers to measure battery charge and discharge currents in smartphones, tablets, ...

Inductors and transformers serve key roles in switch-mode power supplies. Ensuring they perform as expected requires thorough in-circuit measurements performed under operating conditions. Here’s what ...

Leakage current is one of the most stringent, yet telling, parameters of possible danger to patients or caregivers. It does not take much electric current flowing through the human body to cause harm.

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 ...

Inrush current effect is common in electric motors. Sometimes, in case of ill-designed electrical wiring systems, switching on the motor may activate the fuse. It is caused by the inrush current – ...
