Conclusion In this experiment four resistors were connected in series and parallel combinations measuring the potential difference across the resistors and the current through the this the current flowing through both circuits and the potential difference of both determined. The theoretical values for the resistors were 890, 207.64, 307.64 and the measured values of the resistances obtained were 893.92, 218.023, 316.46 an then gives a percentage difference of 0.43%, 4.8%, 2.8% and 1.8% respectively
