Electric current question?

Question

In the equation for current I=Ne/t, where I is current, N is the number of elementary charge, e is elementary charge (1.6 x 10 to the power of -19), and t is time, what does N represent and how do I calculate it?

Answer 1

I=Ne/t. So It = Ne and N = It/e
N = (number of ampère) x (number of seconds) / (1.6 x 10^-19 C)
N is a real number without unit.

Answer 2

In an electric current the flow of electron per second is based on a cross sectional area of a conductor. N would be the number of electrons that would be distributed on that area of the Electrical conductor.
The letter e represent the energy of mIotion of one electron.
In the circuit the number of electrons flowing depends on the circuits conductance of the conductor.The electron does not move more than one electron diameter till it collide s with another electron. So the electric current is a series of collison of electrical masses.

To calculate N you need to know the power of the circuit in terms of Amperes. Divide that by the energy per unit charge then multiply it by the time that the electrons flow in the circuit.

Answer 3

N is the number or electrons flowing past the point you're measuring. You can't count them so all you can do is measure the current for a given amount of time and calculate N. Ne is sometimes referred to as the charge q.

Answer 4

hello, my friend, remember when a current of one ampere is flowing through a wire for one second total numbers of electrons flowing through it is 6.23 x 10 raised to the power 18 approximately ?
