The shape of the voltage-current graph for a conductor is ___________.

Correct option is B

The correct answer is (B) Linear.

The shape of the voltage-current graph for a conductor is linear.

This is a direct consequence of Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage across it, provided the temperature and other physical conditions remain constant.  

Mathematically, Ohm's Law is expressed as:  

$$V = IR$$​

Where:

• V is the voltage across the conductor
• I is the current flowing through the conductor
• R is the resistance of the conductor  

This linear relationship between voltage and current results in a straight-line graph when plotted, with the slope of the line representing the resistance of the conductor.
