Capacitors

The problem is capacitors have a much lower energy density than batteries; they just can''t pack as much energy as an equally sized chemical battery (but that gap is narrowing!). The upside of capacitors is they usually lead longer lives than batteries, which makes them a better choice environmentally.

8.2: Capacitance and Capacitors

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}.
