UNIT OF ELECTRIC CURRENT IS
 A METER B AMPERE C LUX D LUNINESCENCE
Explanation:

Detailed explanation-1: -The ampere is a measure of the amount of electric charge in motion per unit time ― that is, electric current. But the quantity of electric charge by itself, whether in motion or not, is expressed by another SI unit, the coulomb (C). One coulomb is equal to about 6.241 x 1018 electric charges (e).

Detailed explanation-2: -The unit of current is Ampere. Ampere is denoted as “A”. One ampere measures the flow of electric charge across a surface at the rate of one coulomb per second. 1 Ampere = One Columb (C)/One second (S).

Detailed explanation-3: -One ampere of current represents one coulomb of electrical charge, i.e. 6.24×1018 charge carriers, moving in one second. In other words, “an ampere is the amount of current produced by the force of one volt acting through a resistance of one ohm”.

Detailed explanation-4: -If one coulomb of charge flows through a conductor in one second, the current flowing through the conductor is known as one ampere (1A).
