Demonstration
Using PASCO kit (low frequency a.c. voltage), it should be possible to trace out Italic textI - VItalic textCharacterist graphs for a metal wire at constant temperature, a filament lamp and semiconductor diode.
Resources
Analysis
Using the laptops, it should be possible to save the data and print the graphs, or alternatively to export the data and plot graphs in excel, which can then be printed out and kept.
Equipment
Safety
Class Experiment
To take and plot charateristic data for an LDR and thermistor.
Resources
Analysis
Using a light meter, it should be possible to plot a resistance - intensitiy graph for the LDR. For the thermistor, it should be possible to plot a graph of resistance against temperature.
