The graphs between current (I) and voltage (V) for three linear resistors 1, 2 and 3 are given below :
If R₁, R₂, and R₃ are the resistances of these resistors, then which one of the following is correct?
”R₁
”R₃

From the graph, line 1 has the steepest slope, followed by line 2, and line 3 has the shallowest slope.
Slope₁ > Slope₂ > Slope₃
Since Slope = 1/R, this implies:
1/R₁ > 1/R₂ > 1/R₃
Taking the reciprocal reverses the inequality signs:
R₁ < R₂ < R₃ Therefore, the order of resistances from largest to smallest is R₃ > R₂ > R₁.
