Current is measured in which unit
WebDec 12, 2024 · Unit of Current: Electric current is measured in a SI unit known as an ampere, hence Unit of Current is Ampere or A. It is determined by assuming that the elementary charge, e, has a fixed numerical value of 1.602 176 634 x 10 -19 when expressed in the unit C, which is equivalent to the second in terms of ΔvCs. Electric … The ampere is named for French physicist and mathematician André-Marie Ampère (1775–1836), who studied electromagnetism and laid the foundation of electrodynamics. In recognition of Ampère's contributions to the creation of modern electrical science, an international convention, signed at the 1881 International Exposition of Electricity, established the ampere as a standard unit of electrical measurement for electric current.
