Question
Science Question on Ohm’s Law
Study the I-V graph for three resistors of resistances R1, R2 and R3 and select the correct statement from the following:
A
R1 = R2 = R3
B
R1 > R2 > R3
C
R3 > R2 > R1
D
R2 > R3 > R1
Answer
R1 > R2 > R3
Explanation
Solution
From the slope of the I-V graph:
R=IV.
The steeper the slope, the higher the resistance. Based on the graph:
R1>R2>R3.
