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 ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

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, ...

With their low equivalent series resistance (ESR), which allows for good ripple-current handling as well as high surge-voltage ratings and self-healing properties, film capacitors are strong ...

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 ...

You don’t see them much anymore, but there was a time when any hobbyist who dealt with RF probably had a grid dip meter. The ...

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.
