Final answer:
The statement is true; an ampere is the flow of one coulomb of electric charge per second. The relationship is fundamental for calculations involving electric current in circuits.
Step-by-step explanation:
The statement 'The flow of electric charge that is equal to one coulomb per second is an ampere' is true. An ampere is a unit of electrical current in the International System of Units (SI) and it is defined as the flow of one coulomb of electric charge through an area in one second. This relationship between amperes, coulombs, and seconds tells us how electric charge moves in an electric circuit. For instance, if an amount of charge equal to 45 C moves past a point in a circuit in 1 second, we know the current in the circuit is 45 A.
Using the symbol 'I' to denote current, we can represent this as I = 1 C/s, or 1 A. This same principle can be applied to calculate currents in various scenarios, such as the current in a truck battery, or determining the number of electrons flowing through a circuit based on a known flow of charge.
