- Research Question: - How does the length of a wire affect the resistance of the circuit? Hy pothesis If the length of the wire increases, then the resistance will also increase. Variables being tested: Independent variable: Length of the wire Dependent variable:Resistance Controlled variable: Temperature - Ensure that the temperature remains constant throughout the experiment, as it can affect the resistance of the wire. Material of the wire - Use the same type of wire for all measurements to maintain consistency. Potential difference (volts)- Keep the potential difference across the wire constant to eliminate its influence on the results. Materials The list of materials used in the lab includes a power supply.meter stick, wire, alligator clips, cables, data table, voltage readings, and current readings. Procedure To collect data in this experiment, I followed these steps: Begin by ensuring that the power supply is turned off for safety purposes. Connect the alligator clips to the wire on the meter stick and carefully record the length of the wire on the provided data table. Set the power supply voltage to 2 volts before turning it on . Once the voltage is set, turn on the power supply to provide the necessary electrical current. Collect the voltage and amperes readings directly from the power supply. There is no need to connect additional meters such as an ammeter or voltmeter. Record the collected voltage and amperes readings accurately for further analysis and interpretation.
