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 ...

You can use the inherent capacitanceof an LED to make a seriesresonant boost circuit that can create avoltage large enough to light the LED.Depending on the color of the LED, youneed a voltage higher ...

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 ...

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, ...

Electronic circuits are integral parts of nearly all the technological advances being made in our lives today. Television, radio, phones and computers immediately come to mind, but electronics are ...

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 ...

The size of a capacitor affects how much charge it can store (its capacitance), its voltage rating, and its physical ...

As the world shifts toward sustainable transportation, electric vehicles (EVs) have emerged as a key solution to reducing greenhouse gas emissions. However, one major hurdle remains: efficient and ...

In a way, the magic of a soil moisture sensor’s functionality boils down to a simple RC circuit. But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how ...
