Q1) Ohm's Law (in electricity) states that the current (I) is proportional to the applied voltage (V). The constant of proportionality is the resistance (R). The resulting equation is: V = IR. This equation is re-arranged to: I = (1/R) V. Since this is a linear equation, the plot between V (on the x-axis) and I (on the y-axis) should be a straight line, with the slope being 1/R. In an experiment, the following data has been obtained for current for different values of the voltage. Voltage 1 2 3 Current 0.8 2.5 2.9 4.2 5.6 a) Determine the equation for the best-fit line from this data, by using the method of least squares. Equation: Plot the data points, and the straight line representing the equation that you found in part b) 'a'. (Note: the best-fit line will not pass through all the data points) c) Use the slope of the line to find the resistance. Resistance: LO
