find the drift velocity of the electrons in the copper wire (there are 8.5*10^28 free electrons per m^3 in copper)
Unless you hook it up to a voltage source the answer is zero
To find the drift velocity of electrons in a copper wire, we need to consider the relationship between current, electron charge, cross-sectional area, and electron drift velocity.
The drift velocity (vd) of electrons is given by the formula:
vd = I / (n * A * q)
Where:
- vd is the drift velocity of electrons
- I is the current flowing through the wire
- n is the number density of free electrons in the wire
- A is the cross-sectional area of the wire
- q is the charge of an electron
Given information:
Number density of free electrons, n = 8.5 * 10^28 electrons/m^3
Cross-sectional area, A = {Assume a specific value} (e.g., 1 mm^2 = 1 * 10^-6 m^2)
Charge of an electron, q = 1.6 * 10^-19 C (coulombs)
Assuming we have the current value flowing through the wire (I), we can substitute the given values and calculate the drift velocity.
Note: The given information does not provide the current value, so you would need to know or assume a specific current for a concrete calculation.
Please provide the current value to proceed with the calculation.
