Capacitors

Capacitance Units. Not all capacitors are created equal. Each capacitor is built to have a specific amount of capacitance. The capacitance of a capacitor tells you how much charge it can store, more capacitance means more capacity to store charge. The standard unit of capacitance is called the farad, which is abbreviated F.

18.5 Capacitors and Dielectrics

We can see from the equation for capacitance that the units of capacitance are C/V, which are called farads (F) after the nineteenth-century English physicist Michael Faraday. The equation C = Q / V C = Q / V makes sense: A parallel-plate capacitor (like the one shown in Figure 18.28 ) the size of a football field could hold a lot of charge ...

How to test a capacitor: 5 ways with and without a multimeter

Since capacitors block direct current and pass alternating current on, they have different functions. In an alternating current circuit the capacitor is used as an alternating current resistor, in a direct current circuit it can store an electrical charge. This stored voltage is called electrical capacitance (C) and is measured in Farad (F).
