Our Take

A capacitor is a device designed specifically to exhibit a certain capacitance while minimizing its unwanted resistance and inductance characteristics. Their capacity is measured in farads, which is defined as when one coulomb of charge creates a one volt differential. Traditional capacitors have relatively small capacities, much less than one farad, but supercapacitors, a hybrid capacitor of sorts, can have thousands of farads of storage. Capacitors can be nearly too small to see while supercapacitors can be anywhere from coin sized up to large enough to make people think they’re a drinking bottle. Capacitors have a similarly wide variations on the voltages they can withstand.
