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

according to newton's law of inertia, a railroad train in motion should continue going forever even if its engine is turned off.

Unless acted upon by an external force, an object in motion tends to stay in motion, and an object at rest prefers to stay at rest.

We can also see that we regress when a car abruptly begins to move from a condition of rest. The inertia of repose also contributes to this. Our bodies have a tendency to stay in a condition of rest, but as soon as the automobile starts moving, we start to regress.

Unless influenced by an imbalanced force, an item at rest stays at rest, and an object in motion keeps moving in a straight path at a constant pace. Second Law of Motion by Newton.
