When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

Measuring tiny differences in high-voltage circuits usually requires specialized differential test probes, which are often expensive. Fortunately, it’s possible to build your own high-voltage probe ...

This circuit is based on a PIC16F883 that controls a simple lock-in circuit to measure in circuit the ESR and in some cases the capacitance of electrolytic capacitors. The circuit has been designed by ...

Learn how to test a transformer: insulation resistance, TTR, winding resistance, polarity, continuity, and dielectric checks.

A sudden air conditioner failure during the peak of an Orange Beach, AL, summer is more than just an inconvenience; it is a ...

Occasionally a design requires capacitors that are much closer to being identical in value to one another than the usual ...

Vishay’s SMDY1 automotive-grade safety capacitors for EMI/RFI suppression and filtering offers a Y1 rating in a surface-mount ...

Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...

Abstract: For applications like 1500V PV inverter, the 650V GaN device can be utilized in the flying capacitor (FC) stage of an ANPC converter, offering efficiency and power density improvements. This ...

Blood glucose monitoring is an essential tool for managing diabetes. It helps identify how your blood sugar levels respond to factors like diet, exercise, and medications so you can change your ...

Abstract: This work presents an on-chip capacitance measurement methodology for a metal-oxide-metal (MOM) capacitor based on ring oscillator measurements. This time ...
