Question

A copper wire has a circular cross section with a radius of 3.75 mm. The equation for drift velocity is given below.

vd = I nqA A copper wire has a circular cross section with a radius of 3.75 mm. The equation for drift velocity is given below. (a) If the wire carries a current of 4.00 A, find the drift speed of the electrons in the wire. (n = 8.46 A copper wire has a circular cross section with a 10^28 electrons/m) m/s (b) All other things being equal, what happens to the drift speed in wires made of metal having a larger number of conduction electrons per atom than copper? Explain.

Explanation / Answer

according to given formula

after substituting the given data drifr speed is6.6*10^-6 m/s

B) yes the drift speed will be decreased when wires made of metal having a larger number of conduction electrons per atom than copper
