In an experiment, a sample of wire has a resistance 20`(Omega)` at `15^(@)C`. If the experiment is conducted keeping the same wire sample at a temperature of `30^(@)C`, then the possible value of its resistance can be:

A

`20Omega`

B

`10Omega`

C

`15Omega`

D

`22.5Omega`

Text Solution

Verified by Experts

The correct Answer is:
