Question

A student carries out an experiment and plots the V-/ graph of three samples of nichrome wire with
resistances R1, R2 and R3 respectively as shown in figure. Which of the following is true?
R
R
(ampere)
R
V (volts)
Select one:
O a. Ri> R2 > R3
b. R2 R3 RA
c. R3 > R2 > Ri
d. R = R2 = R3​

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
