If you recall, the basic structure of a capacitor is two plates close together with a dielectric between them. We can define an overlapping area of the two plates as A, a gap between the plates as d, and the permittivity (polarizability) of a dielectric as ε.
What is the value of a capacitor?
When it comes to importance, the nominal value of the Capacitance, C of a capacitor will always rank at the top of capacitor characteristics. This value can be measured in three ways: These values are printed directly onto the body of the capacitor in letters, numbers, and colored bands.
What is the capacitance of a capacitor?
The capacitance of a capacitor can change value with the circuit frequency (Hz) y with the ambient temperature. Smaller ceramic capacitors can have a nominal value as low as one pico-Farad, ( 1pF ) while larger electrolytic’s can have a nominal capacitance value of up to one Farad, ( 1F ).
