Planning The aim of my investigation is to investigate how the brightness (intensity) of light shining on the LDR (Light Dependant Resistor) affects the Resistance. We can change the intensity using different methods. One method is to increase the voltage, by plugging the power supply to a higher voltage. But this method can be hard as you might not be able to know how higher the voltage is, it might be harder to have access to higher voltage, as it is dangerous. Another way is to change the brightness by adjusting the power supply. Also the distance between the bulb and the LDR is another method, if the distance is bigger, the less bright it would be. If the distance is less/smaller, the denser it will be. We could also use different bulbs and power supply, with a higher voltage and energy, the higher the voltage, the brighter the light bulb. But this...
