Calculate the measured resistance of a resistor and verify the Ohm's law. Please see attached file.

On a separate piece of graph paper, plot V against I and connect the points with a smooth curve. The V-I curve for two elements in series can also be calculated from the V-I curve of the individual elements. For a given value of I, the separate voltages V1 and V2 across R1 and the light bulb, respectively, are found from the V-I curves in part I. When these elements are connected in series, the current I is the same in both of them, so the potential across the two together is V = V1 + V2. Calculate V = V1 + V2 from the V-I curves in part I for five values of I. Plot these V-I values on the graph with the measured V-I curve for the two elements in series. The calculated points should lie on the measured curve
