Cross Sectional Area Length Figure 2 Then the cross sectional area of the wire can be calculated using the equation of the area of a circle: A = ar? (5) In this experiment, you will measure V and I to determine R for various lengths of wire. You will then make a graph of Resistance (Y-axis) versus length (X-axis). The plot will result in a straight line that has a slope equal to slope = A (6) From equation 6, it is possible to solve the resistivity in terms of the slope and the cross sectional area: p = slope * A (7) The manufacture values of the resistivity corresponding to the wires used in the experiment are reported in Table 1. These values will be used as the theoretical when calculating percent error. Table 1. Theoretical resistivity of different materials according to manufacturer.

5. Assume that you need to measure an average temperature in a heated space. You have three identical temperature sensors. Each sensor produces a voltage proportional to temperature such that: Sensor Voltage = .01 * Temperature in degrees Celsius Assume that you bave three voltages, Va, V, and V, You want to take the average of these three voltages lin order to compute the average temperature inside the heated space. This circuit has been suggested as a possibility for computing the average. Rf ww Vout A. Find an analytical expression for Vout in terms of the input voltages and the four resistors. B. Determine if a proper dhoice of resistors will let you use this as a averager. If you can, then find some appropriate values for the resistors.
