B. under certain voltage conditions, the current in the conductor is inversely proportional to the resistance of the conductor. C. The current in the conductor is determined by the voltage and resistance at both ends. D. the current in the conductor is independent of the voltage and resistance at both ends

A. For a certain section of conductor, that is, the resistance of the conductor is constant, according to Ohm's law, the current in the conductor is proportional to the voltage at both ends of the conductor; B. under certain voltage conditions, according to Ohm's law, the current in the conductor is inversely proportional to the voltage at both ends of the conductor; CD, according to I = ur, the current in the conductor is determined by the voltage at both ends of the conductor and the resistance of the conductor; So C is right and D is wrong
