To determine what a current of one ampere is equal to in terms of the flow per second, let's break down the concept of what an ampere represents.
1. Understanding Ampere: An ampere (A) is a unit of electric current in the International System of Units (SI). One ampere defines a flow of electric charge.
2. Electric Charge: The electric charge is defined in terms of coulombs (C). One coulomb is equivalent to the charge of approximately [tex]\(6.242 \times 10^{18}\)[/tex] elementary charges (such as electrons).
3. Flow of Charge:
- When we say there is a current of one ampere, it means that there is a flow of one coulomb of electric charge per second through a conductor.
Having reviewed these points:
- Ohm is a unit of electrical resistance, not current.
- Electron is a subatomic particle, not a measure of current or flow per second directly.
- Volt is a unit of electric potential or electromotive force, not related to the flow per second directly.
Thus, a current of one ampere is equal to the flow of one coulomb of electric charge per second. Therefore, the correct answer is:
O coulomb
