Problem
A student records the following pairs of potential difference V and current I for two conductors.
Conductor X: (2V,0.4A),(4V,0.8A),(6V,1.2A)
Conductor Y: (2V,0.5A),(4V,0.9A),(6V,1.2A)
Which statement about their behaviour is correct?
(a) Both X and Y obey Ohm’s law equally well
(b) Only X obeys Ohm’s law more closely than Y
(c) Only Y obeys Ohm’s law more closely than X
(d) Only X does not obey Ohm’s law, whereas Y does
