An aluminum wire with a diameter of 0.115 mm has a uniform electric field of 0.215 V/m imposed along its entire length. The temperature of the wire is 550C. Assume one free electron per atom. (a) Use the information in this Table of Resistivities and Temperature Coefcients to determine the resistivity (in Q ' rn) of aluminum at this temperature. p = lapse-08 l x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error (2 - m (b) What is the current density (in MA/mz) in the wire? J = lam l x Your response differs from the correct answer by more than 10%t Double check your calculations MA/m2 (c) What is the total current (in mA) in the wire? I = l74.e l x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. mA (d) What is the dri speed of the conduction electrons? vd = lgoo x Your response differs from the correct answer by more than 10%. Double check your calculations. urn/s (e) What potential difference must exist between the ends of a 2.30 m length of the wire to produce the stated electric field? Av: 0.494 V v
