Problem

Four sets of potential difference (V) and current (A) readings are obtained for the same conductor. A.

(1.0,\,0.18),\;(2.0,\,0.40),\;(3.0,\,0.56)

(1.0,\,0.16),\;(2.0,\,0.32),\;(3.0,\,0.48)

(1.0,\,0.22),\;(2.0,\,0.30),\;(3.0,\,0.43)

(1.0,\,0.25),\;(2.0,\,0.48),\;(3.0,\,0.75)

Which set of readings is most consistent with the behaviour of an ohmic resistor? a) Set A b) Set B c) Set D d) All four sets
