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?
