Capacitance, or capacitance rating, is the amount of energy that can be stored in the capacitor. The higher the capacitance rating, the more energy that can be stored. Generally speaking, you should always replace like-for-like when it comes to capacitors – meaning if your capacitor has a capacitance rating of 10μF, you should …
If the capacitor is a cube of side D, then the capacitor volume is D 3 = Ad and D = (Ad) 0.333 = (1.5×10-3 × 2×10-5) 0.333 ≅ 3.1 mm. To simplify manufacture, such capacitors are usually wound in cylinders or cut from flat stacked sheets.
Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation ref{8.4}.
