The temperature coefficient of resistant...

The temperature coefficient of resistant of wire is `12.5 xx 10^(-4) // C^(@)`. At `300 K` the resistance of the wire is `1 ohm`. The temperature at which resistance will be `2 ohm` is

A

`827K`

B

`854K`

C

`527K`

D

`1127K`

Text Solution

Verified by Experts

The correct Answer is:

D

`alpha=(R_(2)-R_(1))/(R_(1)t_(2)-R_(2)T_(1)), , 12.5xx10^(-4)=(1)/(t_(2)-54)`
