QUESTION 6 The allowed safe current for a No. 3 copper wire, 0.2294 inch in diameter, is 100 A. How many coulombs of charge pass a cross-section of the wire in 0.5 minutes? Assume the electron concentration in copper wire is about 2 x 102④ electrons/in3, the average electron velocity is about 2.5 inches/s, and the charge per electron is 1.6x 1019 C. (Enter your answer as a number with the coulombs units.)
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.)

A long wire carries a current in the direction shown above. The current I varies linearly with time t as follows: I=ct, where c is a positive constant. The long wire is in the same plane as a square loop of wire of side b, as shown in the diagram. The side of the loop nearest the long wire is parallel to it and a distance a from it. The loop has a resistance R and is fixed in space. a. Determine...
An infinite straight wire carries a current I that varies with time as shown above. It increases from 0 at t = 0 to a maximum value I_1 3.3 A at t = t_1 = 12 s, remains constant at this value until t = t_2 when it decreases linearly to a value l4 = -3.3 A at t = t_4 = 31 s, passing through zero at t = t_3 = 24 s. A conducting loop with sides W...

The diagram above shows two wires; wire 1 and wire 2. The charge carriers in wire 1 (of circular cross section and radius R) have a drift speed down the wire that is not constant across the wire. Instead, the drift speed rises linearly from zero at the circumference (r = R) to v_0 at the center (r = 0), according to v_d(r) = v_0(l-r/R). A second wire (wire 2) has the same radius, the same density of charge carriers...
