Thoughtful reader Raymond Laagel of Mulhouse, France sent a note with a proof of a Design Idea we published back in 2010. The DI was called Circuit measures capacitance or inductance, and it was by ...

The capacitance meter generates two signals; one of them lags the other by 60°. A 3-bit, self-correcting, divide-by-six twisted-ring counter comprising IC 6, IC 7, and IC 13B provides the lagging ...

That said, measuring capacitance against a voltage isn’t something any ‘ol meter can do, and we’re glad [limpkin] could put together an easy to use tool that measures this phenomenon.

Electrostatic Potential and Capacitance Class 12 Formula Sheet. Work done, where W is work done, F is the force applied Potential Energy Difference, where U is the potential energy and P and R are ...

My JYE Tech capacitance meter works almost as well as the one I remember from the shop. My no-name AVR-Transistor testor is almost as good of a capacitance meter as the JYE Tech!

Capacitance is typically 0.31pF (oV, 1MHz, 25°C – 0.45pFmax), and operation is across -55 to 150°C. Electrostatic discharge rating to IEC 61000-4-2 s 10kV for contact discharge and 15kV for air ...

Because the capacitance and charge–discharge rates of EDLCs scale with surface area and electrical conductivity, respectively, porous carbons such as activated carbon, ...
