A metallic wire of diameter 0.02 m contains 10^28 free electron per cubic meter. find the drift velocity for free electrons , having an electric current of 100 A flowing through the wire .
Added by Manuel A.
Step 1
You are given: - The diameter of the metallic wire, which is 0.02 meters. - The number of free electrons per cubic meter in the wire, which is \(10^{28}\). - The electric current flowing through the wire, which is 100 Amperes (A). Show more…
