What can I-R Graphs Show you? Show 3 Examples of Some I-R Graphs (Wire & Resistor Graph) (Filament Lamps Graph) ( Diode Graph)

-This can Visualise the Current changes due to the Potential Difference -1st Example, Wires and Resistors. This is a Linear Graph. The Current is Directly Proportional to the Potential Difference [Temperature has to be Constant] This line can be Steep [Less Resistance] or not [High Resistance] , which comes from the Resistance. -2nd Example, Filament Lamps. This is a Non-Linear Graph. The Current increases the Temperature , which increases the Resistance, which makes a Curved Diagram. -3rd Examples, Diode. This is a Non-Linear Graph. Diode will only allow a One Way. If the Lines curves Up at the Positive Side of the Volts, it will be 0 at the Other Side [High Resistance in the Opposite Direction]
