Question asked by Filo student

In an experiment, the current running on a wire is kept constant at a level of 14.3 mA, and the length of the wire is changed. The wire has a diameter of 2.8 mm. For each length, the voltage across the wire is measured. The data collected is given below. For this data set, plot voltage vs. length (V vs. L) and from the slope of the curve, determine the resistivity of the wire. Express your answer using scientific notation with two decimal places in units of Ω·m. V (V) L (m) 0.10 0.14 1.5 0.20 0.26 2.5 0.29 0.37 3.5 0.40 4.00
