Explanation / Answer

PartA - Does Ohm's law apply to this object? Why doyou say so? Since the resistace R is theration between Voltage across the object as the cutrrent I frlowstrought that object R=V/I  
Part B Since the resistace R is theration between Voltage across the object as the cutrrent I frlowstrought that object R=V/I  
Part B How is the resistance of the object relatedto the slope of the graph? Show why. Since R is a slope of the graph above R=(V2-V1)/(I2-I1)
Part C - R is a slope of the graph above R=(V2-V1)/(I2-I1)
Part C - R=(V2-V1)/(I2-I1) Use the slope of the graph to find theresistance of the object. We have since R=(V2-V1)/(I2-I1) R=  (0.60-0.30)/(4x10-3 - 2x10-3 ) R= 150
