Residential building codes typically require the use of 12-gauge copper wire (diameter 0.205 cm) for wiring receptacles. Such circuits carry currents as 20.0A. If a wire of smaller diameter (with a higher gauge number) carried that much current, the wire would rise to a high temperature and cause a fire.

(a) Calculate the rate at which internal energy is produced in 1 m of 12-gauge copper wire carrying 20.0 A.

(b) What if? Repeat the calculation for a 12-gauge aluminum wire.

(c) Explain whether a 12-gauge aluminum wire would be as safe as a copper wire?

25.5 - Copper has 8.5 x 10- free electrons per cubic meter. A 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diam- eter carries 4.85 A of current. (a) How much time does it take for an electron to travel the length of the wire? (b) Repeat part (a) for 6-gauge copper wire (diameter 4.12 mm) of the same length that carries the same current. (c) Generally speaking, how does change ing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?

Residential building codes typically require the use of 12-gaugecopper wire (diameter 0.2053 cm) for wiring receptacles. Suchcircuits carry currents as large as 20 A. If a wire of smallerdiameter (with a higher gauge number) carried that much current,the wire could rise to a high temperature and cause a fire.
(a) Calculate the rate at which internal energy is produced in 2.10m of 12-gauge copper wire carrying a current of 20.0 A.

Your response differs significantly from the correct answer. Reworkyour solution from the beginning and check each step carefully.W
(b) Repeat the calculation for an aluminum wire.

Your response differs from the correct answer by more than 10%.Double check your calculations. WWould a 12-gauge aluminum wire beas safe as a copper wire?
