Detailed explanation-1: -The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 x 10–19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of Cs.
Detailed explanation-2: -An ampere (AM-pir), or amp, is the international unit used for measuring current. It expresses the quantity of electrons (sometimes called “electrical charge") flowing past a point in a circuit over a given time.
Detailed explanation-3: -Starting on May 20, 2019, the ampere is based on a fundamental physical constant: the elementary charge (e), which is the amount of electric charge in a single electron (negative) or proton (positive). The ampere is a measure of the amount of electric charge in motion per unit time ― that is, electric current.
Detailed explanation-4: -We know that ampere is the unit of current. Since this device measures the value in amperes, it’s known as ammeter.
