Question

A student plots V-I graphs for three samples of nichrome wire with
resistances R, R, and R. Choose from the following the statement that
holds true for this graph.
(a)
(b)
(c)
(d)
R = R, = R
R, > R, >R
R,>R, >R
R, > R, >R

Answer 1

See it's clear when you calculate the slope that is ∆y / ∆x = slope of graph

Here, slope of V-I graph will be Resistance .

Hence, The more change in Value of Y with Respect To A Constant value of X . The resistance will be more.

So, R3 > R1 > R2 From observing the graph.

I hope you liked the answer. If it helps make sure to mark it as brainliest if possible.

Happy Preparation!

Have a nice day ahead :)

Answer 2

Your answer is (d)

Resistance is highest in R2

Resistance is moderate in R1

Resistance is lowest in R3

#Above 90%
