| ASSERTION: Resistance of a conductor increases with rise in temperature. |
| REASON: V-I Graph for a conductor at two different temperatures \[{{T}_{1}}\] and \[{{T}_{2}}\] are shown here \[{{T}_{1}}>{{T}_{2}}\]. Graph? |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: C
Solution :
For given V, I is greater for \[{{T}_{1}}\] therefore \[R=\frac{V}{I}\]is smaller for \[{{T}_{1}}\] i.e.\[{{R}_{1}}<{{R}_{2}}\]. Further in case of conductor, the resistance increase with rise of temperature \[{{T}_{2}}>{{T}_{1}}\].
