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
The ratio of the potential difference across the conductor to the current is called resistance
It is defined as the ratio of the potential difference across the conductor to the current. The resistance is measured in Ω.
[tex]R = \dfrac VI[/tex]
Where,
[tex]R[/tex] - resistance
[tex]V[/tex]- voltage (Potential difference)
[tex]I[/tex] - current
Therefore, the ratio of the potential difference across the conductor to the current is called resistance.
