Question

Which expression gives resistance at a changed temperature?

Options

• \[R_T=R_0(1-\alpha\Delta T)\]

• \[R_T=R_0(1+\alpha\Delta T)\]

• \[R_T=R_0+\alpha T_0\]

• \[R_T=\alpha R_0\Delta T\]

Answer 1

Resistance at a changed temperature is given by \(R_T=R_0(1+\alpha\Delta T)\). Here, \(R_0\) is the resistance at the reference temperature.
