Somehow [hvde] wound up with a CB radio that does AM and SSB on the 11 meter band. The problem was ... The answer? An Arduino and a few other choice pieces of circuitry. In particular, [hvde ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

Capacitance meters are instruments that measure capacitance, the ability to store an electric charge. They are used to test, inspect and sort ceramic and other types of capacitors on production lines.

Description: Help prevent failures in motor windings, generators and transformers with a quick and easy resistance test using an Amprobe milliohm meter. To efficiently inspect and verify electronic ...

Salahuddin and Datta found that, under certain conditions, the use of ferroelectric materials leads to a negative capacitance (that is, the voltage of the capacitor decreases as charge is added).

As part of a nationwide roll-out, every home in Britain should be offered a smart meter from their energy supplier by the end of 2025. But what is a smart meter and how do they work? Here's ...

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.
