The resistance R of a light-dependent resistor (LDR) varies with the distance d from a very bright
Question:
The resistance R of a light-dependent resistor (LDR) varies with the distance d from a very bright source of light. It is suggested that R and d are related by the formula R= kdn, where k and n are constants. Design a laboratory experiment to test this relationship. The LDR has a resistance of 50 Ω in bright light and 200 kΩ in the dark.
