Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...

Have you ever found the need to measure the capacitance of a capacitor? No multimeter handy (for shame)? Well, as it turns out you can actually measure capacitance using your Arduino Uno, with no ...

Megger’s new CDAX 605 test set measure capacitance and dissipation factor at high voltages. Faster and easier to use than self-balancing capacitance bridges, the CDAX 605 combines an exceptionally ...

Every now and then you need to make your own capacitor. That includes choosing a dielectric for it, the insulating material that goes between the plates. One dielectric material that I use a lot is ...

ABB has announced the development of a portable capacitance meter, the CB-2000, that is simpler to use and easier to carry than any other measuring devices previously available. ABB has announced the ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

Capacitors are essential components in electronics, primarily used for bypassing and decoupling. Depending on the capacitor type and its application, it is prone to aging and failure. Detecting a ...

An AC bridge circuit can be used to measure the unknown capacitance of a sensor, such as a relative humidity (RH) sensor. Some RH sensors have a transfer function of capacitance vs %RH. Usually the ...

Experimental electrical double-layer capacitances of porous carbon electrodes fall below ideal values, thus limiting the practical energy densities of carbon-based electrical double-layer capacitors.
