A copper wire has a circular cross section with a radius of 1.00 mm. (a) If the wire carries a current of 2.50 A, find the drift speed of the electrons in the wire. (Assume the density of charge carriers (electrons) in a copper wire is n

Complete question is;

A copper wire has a circular cross section with a radius of 1.00 mm.

(a) If the wire carries a current of 2.5 A, find the drift speed of the electrons in the wire. (Assume the density of charge carriers (electrons) in a copper wire is; n_e = 8.46 × 10^(28) electrons/m³)

V_d = 5.88 × 10^(-5) m/s

Explanation:

We are given;

Radius; r = 1 mm = 0.001 m

Current; I = 2.5 A

Number of electrons per m³; n_e = 8.46 × 10^(28) electrons/m³

Now, formula for drift velocity is;

V_d = I/(A × n_e × q)

Where;

I is current

A is Area = πr² = π × 0.001²

A = 0.001²π

q is electron charge = 1.6 × 10^(-19) C

Thus;

V_d = 2.5/(0.001²π × 8.46 × 10^(28) × 1.6 × 10^(-19))

V_d = 2.5/42524.59815899144

V_d = 5.88 × 10^(-5) m/s

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.

yo yo yo its papaguy in the house lol

okay, ima .

um it shows links to uh so kinda microsoft website is that were ima go or no? ?
