What does the ampere (A) measure in an 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: Amount of an electric current

The ampere (A) measures the amount of an electric current, or the rate at which electric charges flow through a circuit. This option is correct because the unit "ampere" is defined as one coulomb (a unit of electrical charge) per second. Option B is incorrect because electric energy is actually measured in joules (J), not seconds. Option C is incorrect because pressure or force do not play a direct role in the measurement of electric current. Option D is incorrect because resistance is measured in Ohms (Ω), not amperes (A).
