If 1 ampere is equal to how many coulombs per second?

• A. 1 coulomb/sec
• B. 6.25 x 10^18
• C. 100 coulombs/sec
• D. 1000 coulombs/sec

Answer: (B)

The correct answer is that 1 ampere is equal to 1 coulomb per second. In electrical terms, an ampere is defined as the flow of electric charge which amounts to one coulomb passing through a conductor in one second. Thus, when discussing the relationship between amperes and coulombs, it is essential to recognize that the fundamental definition establishes this direct equivalence. While the other choices may present interesting numbers or concepts, they do not align with the standard definition of an ampere. For example, although 6.25 x 10^18 can relate to the number of elementary charges (like electrons) in one coulomb, it is not a relevant measure for the direct relationship between amperes and coulombs in the context of current. The options suggesting 100 coulombs/sec and 1000 coulombs/sec are simply too large for the definition of an ampere, as they imply a much higher rate of charge flow than what is specified by the SI unit of electric current. Therefore, understanding the definition of an ampere as a measure of charge flow allows you to conclude that it directly corresponds to 1 coulomb per second.
