Hint:The ampere is named after André-Marie Ampère (1775–1836), a French scientist and mathematician who pioneered electrodynamics by studying electromagnetic. An international agreement, signed at the 1881 International Exposition of Electricity in honour of Ampère's contributions to the development of modern electrical research, established the ampere as a standard unit of electrical measurement for electric current.

Complete answer:
In the International System of Units, the ampere (abbreviated as amp) is the basic unit of electric current (SI). André-Marie Ampère (1775–1836), a French mathematician and physicist who is regarded as the founder of electromagnetic, was given the name. The ampere is defined in terms of other base units by measuring the electromagnetic force between electrical conductors carrying electric current, as defined by the International System of Units.

The previous CGS system featured two alternative definitions of current, one virtually identical to the SI's and the other based on electric charge, with the unit of charge established by measuring the force between two charged metal plates. One coulomb of charge per second was then defined as an ampere. The coulomb, a SI unit of charge, is defined as the charge carried by one ampere for one second. One coulomb of charge passes through a particular location every second under a current of one ampere.

The charge accumulated (or transferred through a circuit) over a period of time is stated in coulombs, while the constant, instantaneous, and average current are all expressed in amperes (as in the charging current is 1.2 A) (as in the battery charge is 30000 C). The ampere's relationship to the coulomb is the same as the watt's (J/s) relationship to the joule.
\[\text{1}\ \text{A=1}\dfrac{\text{C}}{\text{s}}\]

Hence ampere is the answer.

Note:A stream of charged particles, such as electrons or ions, flowing through an electrical conductor or space is known as an electric current. It's the net rate of electric charge flow through a surface or into a control container that's monitored. Charge carriers are the moving particles, and depending on the conductor, they might be one of numerous sorts of particles. Electrons travelling through a wire are commonly used as charge carriers in electric circuits.
