The plates'' physical dimensions and the dielectric material''s electrical properties determine the capacitor''s value. The unit of capacitance is the Farad . A Farad is a relatively high value of capacitance for many small signal electronic circuits, so much smaller values such as microfarads (µF), picofarads (pF), and nanofarads (nF) are common.
