Capacitors are used to accurately measure the fuel level in airplanes; as the fuel covers more of a pair of plates, the circuit capacitance increases. Squeezing the dielectric can change a capacitor at a few tens of bar pressure sufficiently that …
How do capacitors work?
How do we measure capacitance? The size of a capacitor is measured in units called farads (F), named for English electrical pioneer Michael Faraday (1791–1867). One farad is a huge amount of capacitance so, in …
Measuring Capacitors
Measure unknown capacitors or check for faulty ones using different techniques and instruments. Last month, we touched on capacitors while looking at inductors and how to measure them. We needed that explanation to help understand what was going on with the inductor circuits, but we ran out of space to discuss how to measure capacitors themselves.
Introduction to Capacitors, Capacitance and Charge

To measure capacitors, for example, we want to measure a large dynamic range in impedance, from sub milliohm to >1k ohm, especially at high frequency. But, just a VNWA is not enough. For simple, reliable, and routine capacitor characterization we need the VNA, a fixture board on which to place the capacitors and software to analyze the measurement.

Capacitance is the capacity of a material object or device to store electric charge. It is measured by the charge in response to a difference in electric potential, expressed as the ratio of those quantities. Commonly recognized are two closely related notions of capacitance: self capacitance and mutual capacitance. An object that can be electrically charged exhibits self capacitance, for which t…
