A word about signs: The higher potential is always on the plate of the capacitor that has the positive charge. Note that Equation ref{17.1} is valid only for a parallel plate capacitor. Capacitors come in many different geometries and the formula for the capacitance of a capacitor with a different geometry will differ from this equation.
