Solution: The answer is (c) R3 > R2 > R1
Resistance is inversely proportional to the amount of current flowing through it. Because the highest resistance will result in the least amount of current flow, the correct answer is c).
A student carries out an experiment and plots the V-I graph of three samples of nichrome wire with resistances R1, R2 and R3 respectively (Figure.12.5). Which of the following is true?
(a) R1 = R2 = R3

(c) R3 > R2 > R1
(d) R2 > R3 > R1
(a) R1 = R2 = R3
(b) R1 > R2 > R3
(c) R3 > R2 > R1
(d) R2 > R3 > R1
