    Answer:

    The ratio of the potential difference across a metallic conductor to the current in the conductor is known as.

    B. Resistance.

    Explanation:

    According to ohms law   ” the current  passing through a conductor is directly proportional to the potential difference between the ends provided the temperature of the wire remains constant”.

    What is resistance ?

    Resistance is a measure of the opposition to current flow in an electrical circuit

    what is a resistor ?

    a resistor is a n electric conductor which forms resistance to free flow of electric current, the resistance is measured in Ω
