The ratio of the potential difference across a metallic conductor to the current in the conductor is known as
A)potential drop.
B)conductivity.
C)resistance.
D)electromagnetic force.
E)None of the above choices are correct.

Question

Quizplus · Accepted Answer

The ratio of potential difference (V) to current (I) is known as resistance (R), according to Ohm's law: V = IR. Therefore, the correct option is C. Potential drop refers to the drop in potential or voltage as current flows through a conductor. Conductivity is the ability of a material to conduct electricity. Electromagnetic force is a force associated with moving electric charges, and it is not related to the given ratio.
