How many coulombs flow past a point in one second when one volt of current is applied?

The relationship between volts, coulombs, and current is described by the formula:

[ I = \frac{Q}{t} ]

where ( I ) is the current in amperes, ( Q ) is the charge in coulombs, and ( t ) is the time in seconds. When we say that one volt is applied, we are referring to a potential difference that will cause a current of one ampere to flow with one coulomb of charge passing a specific point in one second.

Since 1 ampere is defined as 1 coulomb per second, applying a voltage of one volt would result in one coulomb of charge passing through a point in the circuit each second, assuming a simple circuit with a resistive load.

Thus, with one volt applied to a circuit and assuming the circuit allows for current to flow freely, it follows that one coulomb indeed flows past a point in one second. This reflects a direct relationship between voltage and the movement of charge, foundational to understanding electrical circuits and behavior.
