If drift velocity of electron as well as charge on electron is very small, how can we still obtain large amount of current in aconductor?

If the electron drift speed is so small and the electron's charge is small, how can we still obtain large amount of current in a conductor?

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : the drift velocity of electrons in a conductor is very small, when its two ends are connected to a battery. Reason : It is because, as the electrons accelerated , they get scattered or defleted on suffering collisions against the positive ions in the conductor

How does drift velocity of electrons in a metallic conductor vary with the rise of temperature?

Since drift velociy of electrons is very small, how then is current established almost the instant a circuit is closed?

How can we say that electric current is due to flow of charge?
