VOLTAGE−CURRENT CHARACTERISTICS
ANALYSIS
2. From the graph for procedure 4 find the slope of the best straight line through the data and determine the resistance, and enter the value in cell C80.
3. From the data for procedure 5 determine the resistance R of the light bulb at five different voltage values by taking the ratio V/I. Enter the values in the table at cells C84:C88.
4. From the data for procedure 6 calculate the resistance R at several positive and negative currents. Enter the values in the table at cells C93:C101.
5. Discuss
the significance of the results of procedure 7, commenting
on the agreement or lack thereof between the results of this procedure
and the resistances computed in Analysis steps 2, 3, and
4.
