Compare the coded value with the measured value using percentage discrepancy. How does the percentage discrepancy compare to the coded tolerance of the resistor? Show a sample calculation. Physics level 1 laboratory Page 1 of 7 Semester I, 2011/12 PC1222: Basic Circuits – Laboratory Worksheet Page 2 of 7 Analysis A2 For each resistor, calculate the ratio of voltage/resistance ( Δ V / R ) . Compare the values you calculated with the measured values of the current I using percentage discrep ancy. Show a sample calculation. Question A1 What can you conclude about the mathematical relationship between current I and resistance R ? State clearly the basis of your answer. Question A2 What were possible sources of experimental uncertainty in this experiment? Would you expect each to make your results larger or to make them smaller? Explain.
