Hence, the electron velocity for aluminum and copper wire is 8.6 x m/sec and 1.9 x m/sec
Given that;
cross-sectional area = 0.00161sqqThecurrentn
The current carried by the conductor = 4 amp
To find;
The electron velocity, assuming the wire to be of copper and aluminum.
Solution;
As we know,
= 8.39 x and = 18.1 x
The current carried in a conductor is given by the equation;
I = eA where
e = charge of an electron, = electron velocity and A = Area of cross-section
=
Putting the values we get,
= = 8.6 x m/sec (for aluminum)
and,
= = 1.9 x m/sec (for copper)
Hence, the electron velocity for aluminum and copper wire is 8.6 x m/sec and 1.9 x m/sec
