In circuit capacitor tester Measure capacitors without removing them from a circuit. The method yields proper values even if ssignificant effects by parallel resistance is present. Estimates of ...

Do you have a need to find faulty capacitors? High ESR can lead to problems. Back in 2002, Elektor published an article about a DIY in-circuit capacitor tester, and the Elektor Lab team designed the ...

Capacitors behave differently than resistors, where resistors allow a flow of electrons through them directly proportional to the voltage drop, and capacitors oppose changes in voltage by drawing or ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

We often run into the situation where there are two capacitors, one of them charged up to some voltage level and the other at some lower voltage level which, for purposes of this discussion, we will ...

Troubleshooting single-phase refrigeration compressors requires a technician to have a proficient understanding of capacitors. The start capacitor is one of two types of capacitors that can be found ...

The gradient of this graph is equal to the capacitance of the capacitor. \(C= \frac{Q}{V}\) And the area under the graph is the energy stored by the capacitor.

A couple of years ago, I had the privilege of designing and building a new, state-of-the-art 50 kW transmitter site facility for KBRT(AM) in the Los Angeles market. The project was well documented in ...
