System Sensor offers a Web-based Voltage Drop Calculator that allows users to quickly and easily lay out audible/visible notification device circuits using the company’s notification appliances. The ...

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 ...

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 ...

You would like to sample a signal that has a very large dynamic range and still make an accurate measurement. The voltage range that you would like to measure ranges from 100 nV to 100 mV. How can you ...

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 ...

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, ...

Q: The left taillight on my pickup is somewhat dimmer than the one on the right side. It’s not bad enough to go through the trouble and expense of having fixed it. But it bugs me. Any chance you have ...
