Quantization Of Electric Charge — the NEET Physics formula with its derivation, variables, validity constraints and worked solver.
Quantization of Electric Charge Applies to all isolated electric charges found in nature. While mathematically discrete, at macroscopic scales, charge distribution appears continuous due to the small magnitude of 'e'. Observation of Millikan's Oil Drop Experiment. Determination that all measured charges are integral multiples of a fundamental unit 'e'. n must be an integer (charge is discrete). Quarks possess fractional charge (±1/3e, ±2/3e) but generally do not exist in isolation. Believing charge can exist in any continuous amount. Confusing the mass of an electron with its charge. Ignoring sign conventions when calculating net charge (electrons vs protons).
