Editing Short circuit (section)

== Related concepts ==
In [[electronics]], the ideal model (infinite [[Gain (electronics)|gain]]) of an [[operational amplifier]] is said to produce a ''virtual short circuit'' between its input terminals because no matter what the output voltage is, the [[difference of potential]] between its input terminals is zero. If one of the input terminals is connected to the ground, then the other one is said to provide a [[virtual ground]] because its potential is (ideally) identical to that of the ground.<ref>{{cite book |title=Basic Electronics |date=March 2011 |url=https://books.google.com/books?id=_zytO-iXdxUC&pg=PA184 |access-date=20 April 2011 |publisher=I.
