A student records the following readings for an unknown conductor at 25∘C.
(i) Complete the table by calculating the ratio IV for each observation.
Voltage V (V): 1.0, 2.0, 3.0, 4.0
Current I (A): 0.10, 0.20, 0.30, 0.40
(ii) From your results, state whether the conductor obeys Ohm’s law. Give a reason based on the values obtained.
(iii) Determine the resistance of the conductor from the set of readings.
