Which of the following is likely to happen when a conductor is connected between the poles of a cell?

A. A potential difference will be established between the ends of the conductor.

B. The conductor will quickly melt.

C. Protons in the conductor will move causing a current.

D. The conductor will develop a resistance.

 

A) a potential difference will be established between the ends of conductor.

Step-by-step explanation

B) option B is is incorrect between a conductor doesn't melt by applying a potential difference across it. Melting will happen if a high current will flow through the conductor for a long time if it is a good conductor.

C) electrons in the conductor moves not protons. So its also incorrect.

D) it is also incorrect because value of resistance mainly depend on the current flowing between the ends of a conductor.
