Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...

Capacitors behave differently than resistors, where resistors allow a flow of electrons through them directly proportional to the voltage drop, and capacitors oppose changes in voltage by drawing or ...

Capacitive sensor technology has evolved markedly over recent years, underpinned by advancements in integrated circuit design and novel measurement approaches. These sensors function by detecting ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Agilent Technologies Inc. introduced the industry's first power device capacitance analyzer that automatically characterizes power device junction capacitances using real operating voltages. Agilent ...

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.

A recently filed patent (Publication Number: US20230314495A1) describes a capacitance measurement circuit that includes an analog front-end circuit, a parasitic capacitor, an analog to digital ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

Capacitive sensor interfaces are critical to the accurate measurement of physical parameters such as pressure, humidity, and force across a broad range of applications including biomedical devices, ...

The video cassette tape was really the first successful home video format; discs just couldn’t compete back in the early days ...

Capacitive supplies are very attractive for applications that don't require isolation from the mains supply. Simple, inexpensive, lightweight, and reliable, they run cool and don't generate ...
