Final answer:
To investigate the relationship between wire length and resistance, a student can perform an experiment and plot a graph to analyze the relationship.
Step-by-step explanation:
To investigate how the length of wire affects resistance, a student can perform an experiment by setting up a circuit with a power supply, ammeter, voltmeter, and a wire of varying lengths. The student would measure the current and voltage across the wire for each length, and use Ohm's Law (V = IR) to calculate the resistance. By plotting a graph of resistance versus wire length, the student can analyze the relationship between the two.
Risk Assessment: The student should make sure to use low voltage to minimize the risk of electric shock. They should also handle the wire and equipment carefully to prevent injuries or damage. Additionally, the circuit should be set up properly to avoid short circuits or overheating.
