Residential building codes typically require the use of 12 -gauge copper wire (diameter 0.2053 cm ) for wiring receptacles. Such circuits carry currents as large as 20 A . If a wire of smaller diameter (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 1.00 m of 12 -gauge copper wire carrying 20.0 A . (b) What If? Repeat the calculation for an aluminum wire. Explain whe

SOLVED: A 5.00-A current runs through a 12-gauge copper wire (diameter 2.05 mm) and through a light bulb. Copper has 8.5 × 10^28 free electrons per cubic meter. (a) How many electrons pass through the light bulb each second? (b) What is the current density in the wire? (c) At what speed does a typical electron pass by any given point in the wire? (d) If you were to use wire of twice the diameter, which of the above answers would change? Would they increase or decrease?

A long, straight copper wire (diameter 2.50 mm and resistance 1.00 ohm per 300 m) carries a uniform current of 25.0 A in the positive x direction. For point P on the wire's surface, calculate the magnitudes of (a) the electric field, (b) the magnetic field, and (c) the Poynting vector, and (d) determine the direction of S.
