Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series. In contrast, when capacitors are placed in series, it is as if the plate distance has increased, thus decreasing capacitance.
Notice from this equation that capacitance is a function only of the geometry and what material fills the space between the plates (in this case, vacuum) of this capacitor. In fact, this is true not only for a parallel-plate capacitor, but for all capacitors: The capacitance is independent of Q or V.If the charge changes, the potential changes correspondingly so that Q/V remains constant.

Another reason to use high-Q capacitors is the reduced thermal noise. All real capacitors have an equivalent series resistance, and this resistance creates additional thermal noise. In applications such as satellite receivers, noise levels are critical and high-Q capacitors are used in order to maintain the desired signal-to-noise ratio.
Y-parameters represent the admittance of a circuit, while Z-parameters represent the impedance. In a parallel circuit, Y-parameters are more commonly used as they are easier to calculate and analyze. Can the Y-parameters of a capacitor in parallel be negative? Yes, the Y-parameters of a capacitor in parallel can be negative.
By applying a voltage to a capacitor and measuring the charge on the plates, the ratio of the charge Q to the voltage V will give the capacitance value of the capacitor and is therefore given as: C = Q/V this equation can also be re-arranged to give the familiar formula for the quantity of charge on the plates as: Q = C x V
