SamHB: "Because of this inverse relationship"? Huh?

New page

'''Capacitance''' is a property of [[electric]] [[circuit]]s that describes how much electricity is stored between two plates or wires. It is defined as '''C=Q/V''', where ''C'' stands for capacitance, ''Q'' for charge, and ''V'' for volume.

Because of this inverse relationship, most capacitors are quite large for their size and still only power circuits in the range of a few microfarads. (The '''farad''', named for [[Michael Faraday]], is the unit of capacitance in the [[SI]] system.) Recently, by packing many curved plates into a single cylindrical capacitor, electronics companies have been able to shrink the volume of a capacitor by factors of two or three, thus producing a corresponding boost in farad capacity. It is now possible to buy capacitors as powerful as one or two farads, and super-small capacitors in the kilofarad range are being developed in [[Britain]].<ref>[http://www.engineerlive.com/news/20026/iec-to-develop-standard-for-supercapacitors.thtml IEC to develop standard for supercapacitors].
