Question

A student carries out an experiment and plots the I-V graph of three samples of nichrome wire with
resistances R1, R2 and R3 respectively. Which of the
following is true?
(a) R1 = R2 = R3 (b) R1 > R2 > R3 (c) R3 > R2 > R1
(d) R2 > R3 > R1

Answer 1

Answer:

Using the relation [R=V/I] , which is inverse of the tangent of the given graph.

As tangent of first is greater than second which is further greater than third, the order of resistance will be [R

3

>R
