Chapter 22 Capacitance, Dielectrics, Electric Energy Storage The capacitance is a measure of how much charge must be put on the plates to produce a certain v between them: The greater the capacitance, the more charge is required. Its value(固有容电本领) depends only on the geometry(几何因素) of plates, dielectric propert!y and not on their e or v. The value of capacitance depends only on the size, shape and relative position of the two conductors, also on the material that separates themChapter 22 Capacitance, Dielectrics, Electric Energy Storage The value of capacitance depends only on the size, shape and relative position of the two conductors, also on the material that separates them.
