If the electric potential difference across a conductor is V, and the rate of the charge flow through the conductor is I, the resistance of the conductor equals:

V = RI

Explanation:

The answer to this question is given by Ohm's Law.

Ohm's Law states that in a conductor, the potential difference across it is directly proportional to the flow of current, according to the equation:

where

V is the potential difference across the conductor

R is the resistance of the conductor

I is the current intensity through the  conductor

From the equation we see that:

- As the resistance of the conductor increases, the current decreases (if the potential difference is kept constant)

- As the resistance of the conductor decreases, the current increases (if the potential difference is kept constant)

it is b. absorbs thermal energy
