If the resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60 v, the current flowing through the circuit is

In the millikan oil drop experiment they determined that every drop had a charge which was a while number multiple of -1.60x10^-19. if a drop has a total charge of -9.60x10^-19 then how many excess electrons are contained within the drop?
