The ratio of the potential difference across a conductor to the current in the conductor is called
A) conductivity
B) resistance
C) charge
D) power

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.

Where,

- resistance

- voltage (Potential difference)

- current

Therefore, the ratio of the potential difference across the conductor to the current is called resistance.

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 results is a decrease in air temperature with an increase of altitude.

explanation:

true is the correct answer
