SUMMARY
The charge of fundamental particles, such as electrons and protons, is determined using the mass-to-charge ratio, particularly in mass spectrometry. The most notable historical experiment for measuring the charge of an electron is Millikan's oil drop experiment, which provided a precise value for the electron's charge. Current methodologies continue to utilize mass spectrometers to analyze the mass-to-charge ratios of particles, confirming the foundational principles established by Millikan.
