Capacitance Range

 

 

Capacitance range is a characteristic of variable capacitors. By contrast, fixed capacitors have only one capacitance value. Capacitance is a measure of the energy-storage ability of a capacitor, given as C = K A/D, where A is the area of the electrodes, D is their separation, and K is a function of the dielectric between the electrodes. The formula yields a result in farads (F), but a farad is so large that the most commonly used values for capacitance range are expressed in microfarads (µf = 10-6F) or picofarads (pf = 10-12F).
