When there exists an electric field in a conductor why do electrons move with constant velocity but not with an acceleration?

Yes some delicate situation. Here we have to take a lot of information into consideration. Actually electrons move at random direction and in the absence of an electric field the net velocity of the electrons will be zero. Hence we can assume the initial velocity to be zero. Now as an electric field is applied then a force of eE is acting on the electron opposite to the field direction. Due to this electrons get accelerated. No doubt about it. But this acceleration is in effect only for a duartion known as relaxation time. Hence the speed picked up will be acceleration x relaxation time.
So this velocity attained in that duration is called as Drift velocity.
Vd = (eE / m )* t.
Here m is mass of electron.
Hence a constant velocity Vd

The flow of electrons through a conductor is called?
electric current
Which metals that are not conductor that did not permit the flow of electric?
If a substance does not permit the flow of electrons, then it is not a "metal".
What allows an electric charge to pass through it easily?
A conductor. This is due to free electrons.
What force is required to cause electrons to move through a conductor?
Electric field, a directional vector
What is a flow of electrons moving along a wire or conductor?
An electric current. <<>> The term used for the flow of electrons through a conductor is amperage.
On the application of electric field to a conductor do the velocity of free electrons increase or decrease?
either is constant

Which particle constitutes the electric current in a metallic conductor?
electrons
What does an electric conductor?
It permits electrons to flow through it easily.
What is produced whenever there is a flow of electrons in a wire?
Electric current is the movement of electrons through a conductor.
What do you call the flow of negatively charged electrons in a conductor?
electric current
Which metals are the best conductor of electric?
If the volume and length of the wire are constant, then silver. If the weight and length of the wire are constant, then sodium is the best conductor.
What is the movement of electrons along a conductor called?
It is called, "electric current", and is measured in "Amperes".
Explain free electron concept and electric current?
the flow of electrons in semi conductor is called electric current. the electrons revolved around the nucleas is called free electrons
Created around a conductor when electrons flow through that conductor?
Then an 'electrical current' is said to be present in the conductor.
