E = Value Units Submit Part B What is the electron drift speed in the wire? Express your answer with the appropriate units. • View Available Hint(s) µA ?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.
