Answer:
I) both conductor are ohmic
ii) conductor A has more resistance because R=V/I
and slope of A is greater
iii) ohm's law
The law states that the current passed through the conductor is directly proportional to the potential difference across the ends of the conductor at constant temperature and pressure.
