Capacitive touch interfaces really took hold after their success in the Apple iPod with its rotary wheel. Since then, touch buttons have made their way into almost every household appliance, ...

EEWeb discusses how capacitors work in AC circuits, alternating currents, and how to calculate capacitive reactance (with formulas). Visit to learn more.

Capacitance in parallel adds total capacitance and boosts energy storage. Learn how this setup improves circuit performance in AC and DC systems.

In circuit capacitance meter part 2-modified with inclusion of inductivity Measuring capcaitors from 1pF to 80mF and/or inductors from 1microH to 40H using a low voltage method that is robust against ...

The new circuit to be connected to the previous one is a pulse repetition rate meter with a “pump” diode. The entire system (see Figure 8) allows us to obtain a negative voltage depending on the ...

But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how capacitive soil moisture sensors work simply, clearly, and concisely.
