Filament Lamp Resistance Graph. Resistance of a Filament Lamp In this lesson we will Describe the currentpotential difference graphs for an ohmic conductor and for a filament lamp. Go back a page.
This example looks at how you can take data from a graph to calculate the resistance at a certain value of potential difference. The resistance is constant. Same reason for a filament lamp because as the current in a filament lamp increases it heats up so the resistance changes so again the I-V graph is not a straight line.
Find the current-voltage graph for a diode.
Describe how the resistance changes with potential difference. Resistance of a Filament Lamp In this lesson we will Describe the currentpotential difference graphs for an ohmic conductor and for a filament lamp. That is plotted by the straight-line portion of the graph through the origin. HttpswwwfreesciencelessonscoukworkbooksIn this video we look at the resistance of a filament lamp.
