Amperes are measured in what units?

Amperes, which are the units of electric current, are defined as the flow of electric charge. Specifically, one ampere is equivalent to one coulomb of charge passing through a conductor in one second. This definition establishes a direct relationship between amperes and coulombs, making the measurement of current straightforward in terms of charge flow rate. The other options do not accurately define amperes: meters/second pertains to velocity, volts/ohm relate to Ohm’s law (which incorporates resistance), and watts/second indicates energy transferred over time. Therefore, focusing on coulombs per second provides the correct context for understanding the measurement of electric current in amperes.
