WebBetween 1909 and 1910 the American physicist Robert Millikan conducted a series of oil-drop experiments. By comparing applied electric force with changes in the motion of the oil drops, he was able to determine the electric charge on each drop. He found that all of the drops had charges that were simple multiples of a single number, the fundamental charge … WebThe specific charge of an electron is 1.6⋅10 ^-19. In 1909, the oil-drop experiment was conducted by Robert Millikan and Harvey Fletcher for the purpose of determining a single electron's specific charge. The experiment is also known today as Millikan's experiment. In Millikan's experiment, two horizontal metal plates were placed on top of ...

WebOil-drop experiment The purpose of Robert Millikan and Harvey Fletcher's oil-drop experiment (1909) was to measure the electric charge of the electron. They did this by carefully balancing the gravitational and electric forces on tiny charged droplets of oil suspended between two metal electrodes. WebMay 31, 2014 · Millikan's experiment determined the charge on the electron. Millikan suspended oil droplets between two electric plates and determined their charges. He used an apparatus like that below: Oil droplets from a fine mist fell through a hole in the upper plate. From their terminal velocity, he could calculate the mass of each drop. Millikan then … ultra high molecular weight uhmw polyethylene
