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 ...

Capacitors are essential components in electronics, primarily used for bypassing and decoupling. Depending on the capacitor type and its application, it is prone to aging and failure. Detecting a ...

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 ...

An old Electronics Designer’s Casebook described a circuit that provided capacitance measurements of 10 pF to 1 µF with 1% accuracy (Reference 1). A number of issues emerged with the circuit during ...

Building a capacitance meter is a great exercise. If you’re feeling quite safe in your digital-circuit-only life, this will push just far enough out of the comfort zone for you to see there’s nothing ...

Powered by a 9V battery or an optional ac wall adapter, the Model 881 handheld tester can be used to measure the equivalent series resistance (ESR) of electrolytic capacitors in or out of circuit. The ...

Matching several capacitors, without needing a really precise value, can be accomplished with a "high-tech" laboratory capacitance meter. But this is cumbersome and overkill, and not everyone has one.

Single-phase motors are common in many industries and can be found in blowers, pumps, fans, lathes, and numerous other types of equipment. Single-phase motor failures or malfunctions can often be ...

ABB has announced the development of a portable capacitance meter, the CB-2000, that is simpler to use and easier to carry than any other measuring devices previously available. ABB has announced the ...
