1.	Following graph was plotted between V and l values, across a wire. Which of the following statement(s) is/are correct regarding this?(A) Value of ratio V/l when the potential difference is 0.8 V is not equal to the value of ratio V/l when the potential difference is 1.2 V.(B) This graph illustrates the non-ohmic law. (C) While plotting this graph, the temperature remains constant. (D) All of these
Answer» Correct option (C) While plotting this graph, the temperature remains constant. Explanation: The ratio of potential difference applied to the wire and current passing through it is a constant. Ohm's law is illustrated by this graph. Hence, temperature must be constant while calculating values.

Answer»

Correct option (C) While plotting this graph, the temperature remains constant.

Explanation:

The ratio of potential difference applied to the wire and current passing through it is a constant. Ohm's law is illustrated by this graph. Hence, temperature must be constant while calculating values.
