Introduction to electromagnetism is a quantity used to determine how a particle will behave in an electric field. There are three possible "types" of charge: positive, negative, and neutral. However, the distinction between positive and negative is by convention only. Electric charge is quantized in units of the elementary charge, formula_1, where a proton has a charge of formula_2 and an electron has a charge of formula_3. The SI unit of charge is the coulomb. The elementary charge formula_1 was first measured by Robert Millikan in his oil drop experiment in which the electric force on the particle is set to exactly counter
Jane (given name) Jane (given name) Jane is a feminine given name. It is the English form of the Old French name Jehanne, which was an old feminine form of the male name Johannes or Ioannes (also the source of the English name John), a Latin form of the Greek name (Iōannēs), which is derived from the Hebrew name יוֹחָנָן (Yochanan), a short form of the name יְהוֹחָנָן (Yehochanan), meaning "Yahweh is merciful".
