question:

Find the number of electrons between two points kept at a potential difference of 20V if 40J of work is done.

given:

work ,w=40 joule

potential difference,v=20 V

to find:

number of electrons

FORMULAE:

  • potential difference=work/ total charge

  • total charge Q=ne

where n is number of electrons

e is the charge of electrons.

e=1.6×10^-19 joules
