capacitance

 (C) [kah-pas″ĭ-tans]
1. the property of being able to store an electric charge.
2. the ratio of the charge stored by a capacitor to the voltage across the capacitor.

ca·pac·i·tance

(kă-pas'i-tans),
1. The quantity of electric charge that may be stored upon a body per unit electric potential; expressed in farads, abfarads, or statfarads.
2. In genetics, a state in the evolutionary context referring to an ability to contain or hold. For example, heat shock protein 90 (Hsp90) acts as a buffer, preventing expression of certain genetic traits by allowing these genetic variations to accumulate and stay silenced under neutral conditions. When the capacitance of Hsp90 is compromised, these cryptic variants are then expressed.

These capacitors, with the industry's largest capacitance, enable reductions in the number of required capacitors and their size, contributing to a reduction in board area.
Using capacitors with a higher voltage rating than might seem to be required can offset the effect of the capacitance reduction by maintaining a higher percentage of its rated capacitance.
In addition to the specific capacitance measurements of the supercapacitor using a two-electrode cell, capacitance measurements were also performed using commercial capacitors of 100, 1000, 4700 and 10000 pF with the aim of validating the system.
It can be seen that the specific capacitance only decreased 19% after 3000 test cycles, which demonstrates that the Co3O4 nanowire has a stronger stability, and it is appropriate for long time capacitor applications in KOH solution.
Meanwhile, a capacitance bridge (AH2700 with a resolution of 1 aF) is used to measure the capacitance.
Besides high specific capacitance, good cycling performance is also an important property for microsupercapacitors.
In Figure 3, the capacitance change of all samples with water wash process for 50V47 [micro] F decreases compared to samples without water wash steps measured at 2.2V of standard bias condition.
For a practical needle-contact capacitance probe, the output signal of the circuit in Figure 1(c) can be expressed by
When the capacitance is large, the splashing-away materials dominated the results.
The scientists analyzed the temperature when the capacitance of the sample reached its peak during temperature scans, as well as the peak capacitance value of each sample.
The radiated electromagnetic noise propagation path from the component to the parasitic capacitance between the automobile body and the earth, which is not discussed in Reference [5], was investigated.
In this machine, they presented a simple method for determining the required serial and shunt capacitance in suitable values to provide voltage regulation or the initial self-excitement [13].
