I have an assignment that is about electricity, circuits and I am totally confused on how to build the circuit to measure the current and voltage i think to find out the resistivity of conductors. the conductors my group and i are using are aluminium, iron, copper, zinc and i forget the last one. the teacher has mentioned that the resources she has for the experiment are all in the same size and stuff so i won't have to worry about measuring out the different metals to keep the variables the same. what i'm wondering is what would the diagram look like connecting the wires, alligator clips, power pack, switch, and other stuff needed to measure the current and voltage to find out the resistivity. I have no understanding of anything electricity and circuit wise so correct me if i'm wrong. I've been to about all relevant websites about circuits and stuff and i don't understand a thing. I've seen videos on youtube about measuring a wire's current and voltage but the resources the guy used in the video, our school does not equip. Here are the list of equipment our school has:
1. alligator clips / Wires (specifically for circuit making) i dont know if alligator clips and the wires are the same thing
2. Power pack
3. Multimeter
4. Voltmeter
5. Ammeter
6. Metals as conductors (pretty much the basic ones, a school might have, just not silver or gold)
7. Light bulbs or are they called LEDS
8. resistors
9. Breadboards
10. Breadboard equipment (wires, resistors, LEDS basic equipment breadboards require to build a circuit)
i have no idea if there would be light bulbs (LEDS i dont know) in the circuit. Let alone know how to draw the diagram, that is why i'm in desperate need of understanding the whole concept. Our teacher has been away and we have a substitute that knows nothing so i have to make do, trying to understand how to draw the diagram and how to make the circuit, measure everything, find the resistance of the conductors, compare and discuss why some metals are better conductors. I've got the written part of the assessment part down, i just need help creating the circuit. My group members are also researching about this. Could you please relate this to Ohm's law and write down the equation and stuff.
If any of you could possibly lend a hand that would be much appreciated. thank you.
