Question

(b). An alloy of copper conductor with deformation has a resistivity of 10mΩ at 27°C. When its temperature increases by 20%, its resistivity increases by 10%. When its impurities increases by 25%, its resistivity shoots up by 30%. Assuming Mathiessen's rule to hold good for the conductor, determine the following; (iii). its resistivity due to deformation scattering.

Step 1

Using the formula: Change in resistivity due to temperature increase = Initial resistivity * (temperature coefficient * percentage change in temperature) Change in resistivity due to temperature increase = 10mΩ * (0.0039 * 20%) = 0.078mΩ Show more…
