Can you explain me what would happen inside the conductor, if the conductor is not in electrostatic equilibrium?

If electric field inside a conductor is not zero, then the conductor is not in electrostatic equilibrium. 

Let us take a conductor and apply a potential difference V across it as shown below.                                                                                    

Now the electric field inside the conductor is not zero. Hence, there is no static equilibrium inside the conductor. Since   , free charges inside the conductor start moving in a direction opposite to the electric field, thus producing conduction current.
