The rate of flow of electric charge is measured in A. Ampere B. Coulomb C. Ampere/coulomb D. Ampere-coulomb

The correct answer is A. Ampere.

An ampere (A) is the SI unit of electric current. It is the rate of flow of electric charge. One ampere is equal to one coulomb of charge per second.

A

An ampere-second (A⋅s) is a unit of electric charge. It is the charge transported by a current of one ampere in one second.

The rate of flow of electric charge is measured in amperes. This is because the ampere is defined as the rate of flow of one coulomb of charge per second.
