Some students connected a length of nichrome wire to a variable power supply to produce between 0.0 V to 10.0 V across the wire. They then measured the current through the wire for several voltages. The students recorded the data for the voltages used and the currents measured as shown in the table.

(a) For each measurement, calculate the resistance.

Voltage V (volts)	Current I (amps)	Resistance R = V/I (ohms)
2.00	0.014
4.00	0.027
6.00	0.040
8.00	0.052	153.846
10.00	0.065
-2.00	-0.014
-4.00	-0.028
-6.00	-0.039
-8.00	-0.051
-10.00	-0.064

(c) Does the nichrome wire obey Ohm's law? If not, for all the voltages, specify the voltage range for which Ohm's law holds.
