The potential difference between 2 plates is 450v, how many electrons are transferred

  • #1

Homework Statement


A capacitor has a capacitance of 2.5x10-8F. In charging process, electrons are removed from one plate and placed on the other plate. When the potential difference between the plates is 450v, hoow many electrons have been transferred?


Homework Equations


C=qV


The Attempt at a Solution


C=qV
q=C/V
q=2.5x10-8/450

So far so good, now how would you convert from a charge q to a number of electrons? (Hint: what's the charge of one electron?)

charge of one electron is approximately 1.6x10^-19C. divide q by the charge for one electron.
