Final answer:
It takes approximately 6.25 × 1018 electrons to produce a single coulomb of charge, based on the fundamental charge of an electron, which is 1.6 × 10-19 C.
Step-by-step explanation:
To answer the question of how many electrons it takes to produce a single coulomb (C), we need to consider the fundamental charge of an electron, which is approximately 1.6 × 10-19 C. The number of electrons required to produce one coulomb of charge can be calculated by dividing 1 C by the charge of a single electron.
This calculation shows that 1 C is equal to the charge of approximately 6.25 × 1018 electrons. So, it would take 6.25 × 1018 electrons to have a combined charge of -1.00 C.
It's important to note that in the universe of observable charges, all charges consist of an integer multiple of the charge of a single electron or proton, which is known as charge quantization. Thus, we can say that a coulomb is a unit that measures the amount of electric charge, and one coulomb is the amount of charge transported in one second by a current of one ampere.
