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

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

• A. 1 Coulomb
• B. 2 Coulombs
• C. 6.25 Coulombs
• D. 0.5 Coulombs

Answer: (A)

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.
