The Correct Option is C
Solution and Explanation
Correct answer: The voltage-current graph is non-linear.
Explanation:
Metallic conductors generally obey Ohm's law, which means the current through them is directly proportional to the applied voltage, provided the temperature remains constant.
As a result: - The ratio of voltage to current remains constant, which is the resistance. - The voltage-current (V-I) graph for metallic conductors is a straight line, i.e., linear. - Their resistance does change with temperature (usually increases with rise in temperature).
So, the false statement is: The voltage-current graph is non-linear.
