Question 90
H

A student plots current on the y-axis against potential difference on the x-axis for a fixed resistor at constant temperature. The line is straight, passes through the origin and has a gradient of 0.25 A/V. What is the resistance of the resistor?

[1]
A

4.0 Ω4.0\ \Omega4.0 Ω, because the resistance is one divided by the gradient

B

4.0 Ω4.0\ \Omega4.0 Ω, because the resistance is equal to the gradient

C

0.25 Ω0.25\ \Omega0.25 Ω, because the resistance is one divided by the gradient

D

0.25 Ω0.25\ \Omega0.25 Ω, because the resistance is equal to the gradient
