Discover how to build a simple device that converts light into electricity using LEDs and diodes. This step-by-step guide demonstrates assembling an LED-diode cluster, connecting it to a capacitor for ...

Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

If you’ve seen a big air-variable capacitor, you may have noticed that some of the plates may have slots cut into them. Why? [Mr Carlson] has the answer in the video below. The short answer: you can ...

Abstract: This letter presents an analog–digital variable capacitor realized by monolithic integration of barium strontium titanate (BST) ferroelectric material and phase change material (PCM) ...

Also known as a trimmer capacitor, these are designed for fine adjustments or calibration in RF Circuits providing the ability to vary capacitance, allowing precise tuning and optimisation of ...
