Copper wires used to transport electrical current heat up because of the resistance in the wire. If a 188-g wire gains 448 J of heat, what is the change in temperature of the wire? Copper has a specific heat of 0.384 Jg-1c-1.
For a technical application, an electrical engineer needs to create a solenoid using copper wire with diameter d 0.500 mm. The resistance of the solenoid needs to be 3.500 and the magnetic field of the solenoid with a current of 2.50 A should be 6.50 x 10-T. Assume the resistance does not change significantly with temperature, and the radius of the solenoid is 1.00 cm. (Use p - 1.70 x 10-40-m for the resistivity of copper.) (a) How many turns...
A) An engineer is designing a product in which a copper wire will carry large amounts of electricity. The resistive heating of a 66 g copper wire is expected to add 520 J of heat energy during a 10-minute operating cycle. What is the temperature increase of the wire? You may use the following information about copper to answer the question: specific heat = 0.385 J g-1 °C-1 density = 8.94 g/cm3 coefficient thermal expansion = 6.5 µm m-1 K-1...
A given copper wire has a resistance of 5.05 Ω at 20.0°C while a tungsten wire of the same diameter has a resistance of 4.69 Ω at 20.0°C. At what temperature will the two wires have the same resistance? Your response differs from the correct answer by more than 10%. Double check your calculations.°C

You have two wires connected end-to-end (in series). Wire 1 is copper and wire 2 is made from a “special” carbon conductor. Wire 1 has a resistance of 0.215 Ω/ft. and is 500 ft. long. Wire 2 has a resistance of 0.141 Ω/ft. and is 700 ft. long. Both of these resistances are measured at 20°C. If the ambient temperature is 99°F, what is the wire’s total series resistance? (FROM AN OLD F.E. EXAM) A reminder that temperatures must be...
