QUESTION 1 The allowed safe current for a No. 8 copper wire, 0.1285 inch in diameter, is 50 A. How many coulombs of charge pass a cross-section of the wire in 2.5 minutes? is 1.6 x 10-19 C. (Enter your answer as a number with the coulornbs units.) Assume the electron concentration in copper wire is about 2 x 1024 electrons/in3, the average electron velocity is about 0.87 inches/min, and the charge per electron

The figure shows wire section 1 of diameter D,-5.50R and wire section 2 of diameter D2-3.00R, connected by a tapered section. The wire is copper and carries a current. Assume that the current is uniformly distributed across any cross-sectional area through the wire's width. The electric potential change Valong the length L-1.50 m shown in section 2 is 13.0 μν. The nurmber of charge carriers per unit volume is 820x 1028 m3. What is the drift speed of the conduction...

Consider a copper wire with circular cross section with radius 0.5 mm, where the conduction electrons in the wire have drift velocity 1 mm/s. Copper has a density of 8960 kg/m3, and copper atoms have a mass of 63.5 amu (where 1 amu = 1.67 x 10−27 kg). (a) How many copper atoms are in one cubic meter of copper wire? (b) Assume each copper atom provides one conduction electron (that is, for each copper atom, one electron is able...
