How much current flows through a wire when one Coulomb flows past a point in one second?

When one Coulomb of charge flows past a given point in one second, this corresponds to a current of one Ampere. Current is defined as the rate of flow of electrical charge. The relationship between current (I), charge (Q), and time (t) is given by the equation I = Q/t.

In this equation, if Q (the amount of charge) is 1 Coulomb and t (the time in seconds) is also 1 second, then the calculation becomes:

I = 1 Coulomb / 1 second = 1 Ampere.

This demonstrates that the unit of current, the Ampere, is precisely defined as one Coulomb of charge passing a point in one second. The Ampere is a fundamental unit of electric current in the International System of Units (SI) and is widely used in electrical engineering.

The other options represent different electrical concepts: the Volt measures electric potential, the Ohm measures resistance, and the Coulomb refers to a unit of charge. Each of these has a distinct definition and does not equate to the concept of current flowing through a wire in the scenario described.
