The volt (V) is a unit that measures what aspect of electric current?

Amount of an electric current
Electric energy being used in 1 second
Pressure or force that pushes the flow of electrons forward
Resistance of an electric current

The correct answer is: Pressure or force that pushes the flow of electrons forward

The correct answer is C, "Pressure or force that pushes the flow of electrons forward." In the context of electric current, voltage (measured in volts) represents the pressure or force that drives the flow of electrons through a circuit. It is essentially the electromotive force that causes the movement of electric charge. This distinction is important as it helps differentiate voltage from other aspects such as the amount of current (choice A), the energy being used (choice B), or the resistance in the circuit (choice D).
