In today’s physics lesson, the focus was on electricity, specifically investigating how the resistance of a light-dependent resistor varies with the distance from the light source. Students began by setting up an experimental circuit that included a torch, a light-dependent resistor, a voltmeter, and an ammeter to measure voltage and current. The lesson emphasized the importance of labeling components in diagrams and understanding the relationship between resistance and distance. Students are encouraged to use a ruler to measure the distance from the torch to the resistor during their experiments.
