→About IV Graphs
===About IV Graphs===
: On an '''IV graph''' the [[Potential Difference|potential difference]] is plotted on the [[x-axis]] and the [[Electrical Current|current]] is plotted on the [[y-axis]].
: An '''IV graph''' can be used to identify the characteristics of an unknown [[Electrical Component|electrical component]]. This may be useful when inventing new [[Electrical Component|components]].
: The [[Electrical Resistance|resistance]] of an [[Electrical Component|component]] can change with the [[Electrical Current|current]] or the [[Potential Difference|potential difference]].
