Key Stage 4

Meaning

An IV graph is a graph showing how the current (I) through a component changes with the potential difference (V) across component.

About IV Graphs

On an 'IV graph the potential difference is plotted on the x-axis and the current is plotted on the y-axis.
An IV graph can be used to identify the characteristics of an unknown electrical component. This may be useful when inventing new components.
The resistance of an component can change with the current or the potential difference.
The resistance of a component can be found by taking the ratio of potential difference to current at a point on the curve.
