Q11 of 35 Page 90

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?

Since the slope of the above graph is inversely proportional to the resistance. As in the graph, slope of R1 is maximum, so resistance will be minimum. Similarly Slope of R3 is minimum, so it will have maximum resistance. So, the correct order is:


R3 > R2 > R1
