Calculate the charge carried by 12.8 x10^8 electrons​

Answer 1

Answer:

Calculate the charge carried by 12.5×10^8 electrons?

One coulomb is the fundamental SI unit of charge. It is defined as the charge in one Ampere of current passed for one second.

Now for an electron, the amount of charge it carries is 1.6*10^-19 C.

So for making a charge of one Coulomb, the number of electrons required will be:

n = 1/(1.6*10^-19)

n = 6.25*10^18 number of electrons

Here, number of electrons is given as 12.5*10^18 electrons. Charge on an electron is 1.6*10^-19 C.

Thus, the charge carried by the electrons is:

Q = n*e

Q = (12.5*10^18)*(1.6*10^-19)

Q = 2 C.
