The resistance of a wire is `5 Omega` at `50^@`C and `6 Omega` at `100^@C` . The resistance of the wire at `0^@C` will be

`3Omega`

`2Omega`

`1Omega`

`4Omega`

Text Solution

Verified by Experts

The correct Answer is:

From the relation `R=R_0[1+ alpha(T-T_0)]`, we have `5 = R_0[1 + 50alpha]` and `6=R_0[1 + 100 alpha] `
