Capacitance is defined as the capacity of any material to store electric charge.The substance that stores the electric charge is called a capacitor, i.e. the ability of the capacitor to hold the electric charge is called capacitance. It is denoted with the symbol C and is defined as the ratio of the electric charge stored inside a capacitor by the …
Capacitors in Series and in Parallel Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}.

Definition of Capacitance Imagine for a moment that we have two neutrally-charged but otherwise arbitrary conductors, separated in space. From one of these conductors we remove a handful of charge (say (-Q)), and place it …
Alternatively, we may think of the length (l) as pertaining to one short section of a much longer structure and thereby obtain the capacitance per length as opposed to the total capacitance. Note that the latter is exactly what we need for the transmission line lumped-element equivalent circuit model (Section 3.4).
Moreover, since the latter formula is exactly the same as for the point charge placed in the sphere''s center, the potential''s distribution in space can be obtained from Eq. (1.35) by replacing ( q) with the sphere''s full charge ( Q). Hence, on the surface of the sphere (and, according to Eq. (1b), through its interior),
