I work a lot with high voltages and others frequently replicate my projects, so I often get asked “What voltage is needed?”. That means I need to be able to measure high voltages. Here’s ...

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 ...

You need to know how to measure the current that flows through a component in a circuit and the voltage across it. The ammeter must be connected in series with the component – remember ...

Feed a known current through the thing you want to measure and read the voltage required. A little math, and that’s it. Or is it? If you are measuring reasonably large resistance and you don’t ...

Lake Shore Cryotronics is aiming at the characterisation of 2D and nano electronic devices with a source measure unit capable ...

sales personnel who are new to process control and measurement. It is also valuable as a concise and easy-to-read reference source on the subject. This new edition provides expanded coverage of ...

Analog voltmeters measure voltage or voltage drop in a circuit. They display readings using a needle rather than a digital display. Voltmeters may be standalone devices or a part of a multimeter.
