| style="height:20px; width:200px; text-align:center;" |The '''IV graph''' for a [[resistor]] shows that [[Electrical Current|current]] is [[Directly Proportional|directly proportional]] to [[Potential Difference|potential difference]].
| style="height:20px; width:200px; text-align:center;" |The '''IV graph''' for a [[Electrical Bulb|bulb]] shows that as the [[Potential Difference|potential difference]] increases the [[Electrical Current|current]] increases. However, at large [[Potential Difference|potential differences]] a change in [[Potential Difference|potential difference]] causes a smaller increase in [[Electrical Current|current]] for a change at small [[Potential Difference|potential differences]].

| style="height:20px; width:200px; text-align:center;" |The '''IV graph''' for a [[diode]] shows that for a positive [[Potential Difference|potential difference]] the [[Electrical Current|current]] increases rapidly with an increase in [[Potential Difference|potential difference]] while for a negative [[Potential Difference|potential difference]] the [[Electrical Current|current]] remains negligible and does not increase as the [[Potential Difference|potential difference]] becomes larger.
| style="height:20px; width:200px; text-align:center;" |The '''IV graph''' for a [[Light Dependent Resistor|light dependent resistor]] shows that at a high [[light]] intensity the [[Electrical Current|current]] increases rapidly with the [[Potential Difference|potential difference]] whereas at a low [[light]] intensity the [[Electrical Current|current]] increases slowly with the [[Potential Difference|potential difference]].
