Discussion
Conclusion
Series circuits
D1) Based on the results, comments on the relationship between V, I and R in a series circuit (3). Does this agree with the theory (2)?
D2) Discussion of the percentage difference between the total nominal resistances and total measured resistances (3). Explanation of the reasons for any difference between the total nominal resistances and total measured resistances (2).
D3) Comments on the value of the measured potential difference across each resistance compared to the calculated p.d across each resistor (3). Discussion of the reasons for any difference between the theoretical (calculated) values and measured values of VS and I in series circuit (4).
Parallel circuits
D4) Bases on the results, comment on the relation between the measured V and I in a parallel circuit (3). Does this agree with the theory (2)?
D5) Comments on the value of the total measured resistance compared to the calculated total resistance (3). Discussion of the reasons for any difference between the theoretical (calculated) values and measured values of V and I (4).
D6) Improvements to the method in order to gain a more accurate/precise result (4).
