Resistance of the wire is measured as

2\,\Omega

and

3\,\Omega

10^\circ \,C

and

30^\circ \,C

respectively. Temperature co-efficient of resistance of the material of the wire is:

View answer and explanation

Correct option: A

0.033^\circ \,{C^{ - 1}}

Option A (

0.033^\circ \\,{C^{ - 1}}

) is correct because the temperature coefficient of resistance is calculated using the given resistance values at different temperatures.
