Question

A student plots V-I graphs for three samples of nichrome wire with resistance R1, R2, and R3. Choose from the following statements that holds true for this graph. a. R1=R2=R3 b. R1>R2>R3 c. R3>R2>R1 d. R2>R1>R3

Answer 1

Explanation:

I think option d. R2>R1>R3 is true

Answer 2

Answer:

d. R2>R1>R3

Explanation:

If it were a V-I graph, i.e V in y axis and I in x axis,

then R3 would have had the greatest resistance.

But here, as it's an I-V graph i.e I in y axis and V in x axis, thus R2 will have the greatest R, then R1 and then R3.

so max. R --> R2

min. R --> R3
