Coulomb per second is equivalent to ______.

ampere

The correct answer is option 3. ampere.

Coulomb per second is equivalent to Ampere.

Ampere (symbol: A) is the unit of electric current in the International System of Units (SI). It is defined as one coulomb of charge passing through a given point in one second. Therefore, one ampere is equivalent to one coulomb per second. Electric current is the flow of electric charge, typically carried by moving electrons in a conductor, and it is measured in amperes.
