What his experiment basically did was determined the size of the charge on an electron. Another thing this experiment did was determined that there was a smallest 'unit' charge. That experiment he did payed of when he the Nobel Prize in 1923. He had a charge on a tiny drop of oil, showing how strong should be applied, the electric field had to be in very perfect order to prevent the oil from falling. Because he was able to work out the mass of the oil drop, and he could calculate the force of gravity on one drop, he could then determine the electric charge, he drop must have. His variation on the charge on different drops, made him notice that the charge was always a multiple, on the charge of a single electron. This meant that always electrons are carrying this
