Question

If one mole of electron passes through a fixed point in a conductor in a specific time duration then how much electric charge has passed through it

Answer 1

Answer

q = - 9.647x10⁴ C

Explanation:

Let

Charge of an electron = e

then, total charge which pass through the cross section is given by

q = Nₐ*e,

where Nₐ is Avogadro's Constant. This is because 1 mole of electron contains Nₐ number of electrons.

q = (6.022*10²³)*(-1.602*10⁻¹⁹) C

= - 9.647x10⁴ C
