Answer the following short questions. a. A rectangular block has a resistivity of ? and resistance of ?. If we scale it up in size by a factor of 2 in every direction, what is the new resistivity and resistance as a function of ? and ?? b. Small aircraft often use 24-V electrical systems rather than the 12-V systems used in automobiles, even though the electrical power requirements are roughly the same. This is because a 24-V system uses...

At a certain temperature T1, a (1.8922x10^2) mm rod of a copper-nickel alloy has a resistivity of (2.770x10^1) x 10-8 Ω-m. For pure copper, the resistivity at 0°C is 1.58 x 10-8 Ω-m and the change in resistivity per degree increase in temperature is 6.50 x 10-11 (Ω-m)/°C. The value of A for nickel in copper is 1.18 x 10-6 Ω-m and the coefficient of thermal expansion of this alloy is (1.543x10^1) x 10-6(°C)-1. If the resistivity of this alloy...

Copper wire has a resistivity ρ = 1.7 × 10-8 Ω⋅m when at 20°C and it has a temperature coefficient α = 3.9 × 10-3 K-1. A solid cylinder of copper of length L = 45 cm and diameter D = 1.5 mm has one end held at T1 = 6°C and the other end is held at T2 = 270°C. The temperature increases linearly between the two ends of the cylinder. Determine the total resistance in milliohms.
