Consider a copper bar with dimensions 15 cm x 19 cm x 90 cm ( A x B x C ). If you are to attach wire leads to this copper bar to make a resistor, to which opposite faces ( A, B, or C ) should you connect the leads in order to:

A) Achieve the largest possible resistance.

B) Achieve the smallest possible resistance.

Consider a sample of pure copper with dimensions of 1 cm x 1 cm x 1 cm. The sample is cold worked and has a dislocation density of 1010/cm2 . After a recrytstallizing anneal, the dislocation density is reduced to 104 /cm2 . If the average dislocation line energy is 5 eV/nm, calculate the energy change associated with this aspect of the recrystallization process. It was said there was not enough information to answer, but this is all that was...

a) In most metals, there is roughly one conduction electron per atom. Consider a copper wire (1 mm diameter) carrying a current of 10 A (these numbers are typical of home wiring) Compute the drift velocity of electrons in this wire. (Is it surprising? Comment, briefly.) b) If I stretch a given piece of copper wire, making it 0.1% longer, how much would this (roughly) change the resistance from end to end? (What assumptions are you making?) c) Suppose I...

Consider the following population: {7, 8, 8, 9, 9}. The value of μ is 8.2, but suppose that this is not known to an investigator. Three possible statistics for estimating μ are Statistic 1: the sample mean, x Statistic 2: the sample median Statistic 3: the average of the largest and the smallest values in the sample A random sample of size 3 will be selected without replacement. Provided that we disregard the order in which the observations are selected,...

Part 1: Two Round Conductors Gather all items required for the exercise. Note: If using the lab kit box, remove contents and place in a secure area. Put on your safety goggles. Center the black conductive paper on the top of the box, grid-side up. Place the two metal nuts (conductors) at the (5 cm, 10 cm) and (20 cm, 10 cm) positions on the paper. Secure using two dissection pins for each conductor. See Figure 13. Note: Place the...
