Learn how to measure current and voltage and the advantages of parallel circuits.

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 ...

Voltage is a measure of the difference in energy between one part of a circuit and another. It tells you how much electrical energy has been converted into other forms of energy. Voltage is measured ...

For more than a century, scientists have relied on separate tools to measure the three core building blocks of electricity: ...

Sense resistors in series with the load can force current sharing between regulators, but using low-side sense elements yields even better results. To improve efficiency in high-power applications, ...

The National Institute of Standards and Technology (NIST) says it can now test voltage, current, and resistance in one device ...

There are many reasons why one would want to measure voltage and current in a project, some applications requiring one to measure mains and even three-phase voltage to analyze the characteristics of a ...

Measuring DC current is not too difficult. Pass the current to be measured through a precision resistor, and measure the voltage drop across it using a sensitive voltmeter. I = V/R So far, so good.

Forbes contributors publish independent expert analyses and insights. Technology journalist specializing in audio, computing and Apple Macs. Plugable is one of those fascinating companies that make ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...
