Ohm's Law (in electricity) states that the current (1) is proportional to the applied voltage (V). The constant of proportionality is the resistance (R). The resulting equation is: V = I R. Since this is a linear equation, the plot between V (on the y-axis) and I (on the x-axis) should be a straight line, with the slope being the value of R. In an experiment, the following data has been obtained for current for different values of the voltage. Voltage 0 1 2 3 4 5 Current 0 0.8 2.5 2.9 4.2 5.6 Determine the equation for the best fit lin e from this data, by using the method of least squares. 6 Plot the data points, and the straight line representing the equation found in part a. 3+3 Use the slope of the line to find the resistance.
