Current = charge / time
Charge q = n * e
e = 1.602 x 10^-19 C
time given = 0.2 s
Current = 0.5 A
So I = n e / t
Hence n = I * t / e
Plug I, t and e. You would get required n
ANS: 6.24 x 10^17 electrons
Q = I*t
2=.5*t
Therefore t=4sec
"2 amperes" means "2 coulombs per second"
(2 coulombs per second) x (2 seconds) = 4 coulombs
If 0.25 coulombs of charge passes through a point in a circuit in 0.5 seconds, then the current is 0.5 amperes. Current is coulombs per second, so divide 0.25 by 0.5 to get 0.5.

electric current
Its called "current"
The motion of electrons is called elecricity. Electricity is used to represent the liberated out put by the movement of electrons.
No, a charged conductor is either at an abundance or lack of electrons. The moment an earth is provided, a discharge begins, which is current flowing.
The terminology for a steady flow of electrons through a conductor is called the current of the circuit.
The free electrons in a conductor will, when a difference of potential (voltage) is applied at its ends, participate in electron current flow (or just current, if you prefer). The voltage applied to the conductor will drive current through the conductor, and the free electrons will support current flow. These electrons will actually move through the conductor. As electrons are driven into one end of the conductor, the free electrons "shift over" and electrons stream out the other end of the conductor. This is the essence of current flow in conductors.

When measuring current, we are measuring the number of electrons (conventionally positive charges) passing through the cross section of the conductor in one second.AnswerActually, the unit of electric current, the ampere, is defined in terms of the force between two parallel current-carrying conductors, and NOT in terms of the quantity of electrons passing a given point!
Electric current is the movement of electrons through a conductor.
TRUE
That description doesn't fit any electrical term, probably because it's not useful.The number of electrons passing a single point in the conductor in one secondis proportional to the electrical current, and is described in units of amperes.
