This Design Idea presents a very accurate, yet very inexpensive, capacitance meter. It was specifically designed for measurements of low value capacitance – with an accuracy of better than 1pF – for a ...

If you need to measure capacitance but don’t have the necessary meter, you may be able to build a circuit that can handle the task. For example, if you have a data-acquisition board or module that ...

If you are just starting out in electronics, you need tools. But it is hard to build all your tools. Even though we see a lot of soldering station builds, you really ought to have a soldering iron to ...

Ever wondered how engineers inspect capacitors, resistors, and inductors? The solution is frequently in a device known as an LCR meter. The tool is quite valuable since it measures three significant ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

Viable cell count (VCC), a critical parameter in both microbial and mammalian cell cultures, fluctuates during batch and fed-batch cultures. VCC is determined conventionally through sampling and ...
