Thanks a lot. I truly appreciate your help.

Yes, but the uncertainty of the voltmeter was ± 0.1

Sorry for all the trouble but could you tell me how do I use this in the first formula? And why did we use the uncertainty of the ammeter with the Voltage ( If it is even the case)? Forgive me but I'm struggling with my lab teacher.

I'll try to do the same experiment again today and rewrite the report. So, would you please tell me what to do this time , what to expect and how to deal with it? What is uncertainty ? How did we get the formula for ΔR for the percentage error ? I think that the second graph is not exact. Is...

Sorry, Could you explain it in more details ? I didn't understand, right from the formula.

Yes, experiment 2 and 3 are different. the resistors in experiment 2 are in series and in 3 in parallel. The question says: comment on your results and calculate the percentage error (ΔR).

I get it now. The voltmeter was: 0.2 - 0.4 - 0.6 then it would be: ± 0.1 but how do I use it ?

So, If the scale is like: 0.02 - 0.04 - 0.06 Then the accuracy = + or - ( 0.01)?

I don't really know what do you mean by accuracy but what I remember that the smallest scale is 0.02 in the ammeter and the highest is 1.

Sorry about it. I put the wrong circuit but it should be fine now. About the R value, I think the teacher made a mistake.

I have some problems with my lab report. The teacher is dealing with us as expert in physics but I don't understand many things. She told us to find the uncertainty and percentage error , even though she didn't explain anything and I'm completely lost. I tried my best but I'm not even sure...
