The charge on an electron is 1.6×10^-19C.Find the number of electrons ...
We know,
q = i × t,
also, q = ne,..
⇒ ne = it
we have,
e = 1.6 × 10⁻¹⁹, i = 2A, t = 1 sec .. and we have to find n,.
so, n = 2/(1.6 × 10⁻¹⁹) = 1.25 × 10¹⁹ electrons..
i hope u understand...

Calculating the Number of Electrons Flowing to Constitute 2A Current
Current is the flow of electric charge per unit time. The unit of current is ampere (A), which is defined as the flow of one coulomb of charge per second. The charge on an electron is 1.6×10^-19C. To calculate the number of electrons that will flow per second to constitute a current of 2A, we can use the following formula:
Current = Charge flow per second
Therefore,
2A = Q/t
where Q is the total charge flow and t is the time taken.
We know that the charge on an electron is 1.6×10^-19C. Therefore, the total charge flow for a single electron is:
q = 1.6×10^-19C
To find the total charge flow for 2A current, we can rearrange the formula as:
Q = It
where I is the current and t is the time taken.
Substituting the given values, we get:
Q = 2A × 1s
Q = 2C
Therefore, the total charge flow for 2A current is 2 coulombs.
Calculating the Number of Electrons
To calculate the number of electrons that will flow per second, we can divide the total charge flow by the charge on a single electron:
n = Q/q
Substituting the values, we get:
n = 2C / 1.6×10^-19C
n = 1.25×10^19 electrons
Therefore, to constitute a current of 2A, 1.25×10^19 electrons will flow per second.
