You connect an unknown resistor to a battery that can provide
the electric potential up to 10 V to form a closed loop circuit m8.5ade of the battery and the resistor. Using an
ammeter to measure the current coming out of the battery and using a voltmeter to measure the electric potential
difference across the resistor. In this experiment you vary the electric potential V provided by the battery from
0 V to 10 V in a step of 2 V. At each step you measure the current I out of the battery. When you plot V (V) vs.
I (A) on a graph, the data points spread evenly around a straight line whose slope is 8.5 V/A. Find the measured
resistance of the resistor in Ohm Keep at least two significant figures. No units are needed for the answer, and you
input just a numerical value for the specified units.
part 2) if the resistor is rated at 10 Ohm by the manufacturer with a possible 5% error on the resistance,
calculate the %difference using your measurement and the rating in %. Keep at least two significant figures. No
units are needed for the answer, and just input a numerical value for the specified units.
