==Key Stage 4==
===Meaning===
An '''IV graph''' is a [[graph]] showing how the [[Electrical Current|current]] (I) through a [[Electrical Component|component]] changes with the [[Potential Difference|potential difference]] (V) across [[Electrical Component|component]].
===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]].
: The [[Electrical Resistance|resistance]] of a [[Electrical Component|component]] can be found by taking the [[ratio]] of [[Potential Difference|potential difference]] to [[Electrical Current|current]] at a point on the curve.
