Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.

A change of 401 C charge pass through an imaginary plane during a time interval of 2.0 minutes. What is the current in amps (coulombs per second)? Current = Charge/time (convert minutes to seconds). Enter units as A or C/s
While tracking the speed of individual particles is great, a more useful and simpler quantity to measure is current which is the amount of charges moving through some cross-sectional area per unit time. It has units of Coulombs per second (or Amps} and is abbreviated by the symbol i. See if you can write out a formula for the current through a section of wire with cross sectional area A given the average speed of particles v, the charge on each particle, q, and the number of charges per unit volume, n. Use dimensional analysis for this formula. Which of the terms in your formula do you think the electric field can influence?
