Battery cell open circuit voltage (OCV) is an important measurement made on the cell during manufacturing to determine cell performance quickly and reliably. Download our application note to learn why ...

A version of Part 1 appeared in the Dec. 2011/Jan. 2012 issue of Test & Measurement World. See the PDF. In January 1979, Electronic Test published an article claiming that a single test circuit that ...

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, ...

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 ...

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 ...

Download this article in PDF format. Many modern servers, as well as telecom and networking equipment, are populated with multiple voltage regulators on the system board to provide power to ICs or ...

Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but measurements must be properly interpreted. With a clamp-on DMM, accurate ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

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