Resistance of a wire coursework

[sueanne]

For the resistance of a wire coursework, i have already done it based on experimenting with different lenghts against resistance. for the evaluation, i need to write an extension on the coursework: i have a few ideas already
• Experimenting with other types of materials of wires to see if they follow the same pattern.
• Find out if non-metallic conductors follow the same pattern as well.
• Find out if there is a relationship with current, resistance and voltage. The experiment can be set up like the potentiometer circuit.

the problem is that i need to come up with a mini-method for one of them, but I am right confused on that, any ideas? it would also be great if its for the first bullet pint

Thanks!

you could try to use different resistors ie. 3 ohms, 5 ohms etc. Well you don't need to look for patterns and proportionalities as you could do that by looking at this formula V=IR

Great job on completing your resistance of a wire coursework! It seems like you have some interesting ideas for extensions to your experiment. Let's take a closer look at each one and see if we can come up with a mini-method for one of them.

1. Experimenting with other types of materials of wires to see if they follow the same pattern.
For this extension, you could choose a few different materials of wires such as copper, aluminum, and steel and measure their resistance at different lengths. The mini-method could involve creating a table to record the different materials, their lengths, and corresponding resistances. Make sure to use the same equipment and set up for each material to ensure accurate results.

2. Find out if non-metallic conductors follow the same pattern as well.
To test this, you could use materials such as graphite, carbon, or even a pencil lead as your conductor. The mini-method could involve setting up a circuit with the non-metallic conductor and measuring the resistance at different lengths. Again, make sure to use the same equipment and set up for each material to ensure accurate results.

3. Find out if there is a relationship with current, resistance, and voltage. The experiment can be set up like the potentiometer circuit.
For this extension, you could set up a circuit with a variable resistor (potentiometer) and measure the current, resistance, and voltage at different settings. The mini-method could involve creating a graph to plot the relationship between these variables. You could also try different materials for the resistor and compare the results.

Overall, the key to coming up with a mini-method is to keep it simple and focused on one specific aspect of your extension idea. I hope these suggestions help, and good luck with your coursework!
