What is the term for the rate of flow of electric charge?

The rate of flow of electric charge is termed "current." This concept is fundamental in understanding how electricity works in circuits. Current is measured in amperes (A) and represents the amount of charge that passes through a conductor in a given amount of time. It effectively indicates how many electrons are moving through the circuit per second.

Additionally, understanding this term helps in distinguishing it from the other choices. Resistance refers to the opposition to the flow of electric charge; voltage measures the electric potential difference that drives current through a circuit, and power indicates the rate at which energy is consumed or transferred in an electrical system. Thus, current specifically quantifies the flow of electric charge, making it the correct response in this context.
