Amperes are measured in what units?

Amperes are measured in what units?

• A. Meters/second
• B. Coulombs/second
• C. Volts/ohm
• D. Watts/second

Answer: (B)

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.
