Which of the following is a FALSE statement about current?

The statement that current is measured in coulombs is false. Current is actually measured in amperes (A), which indicates the amount of charge (in coulombs) flowing per unit time (one second). Specifically, one ampere is defined as one coulomb of charge passing through a conductor in one second. Therefore, while coulombs are related to the electric charge, they do not measure current directly; instead, they quantify the total charge flowing.

The other statements are accurate. Current can indeed be either alternating current (AC) or direct current (DC), which reflects the direction and nature of the electrical flow. Additionally, current does flow from a source of voltage, as voltage acts as the driving force that causes charge carriers (typically electrons) to move. Lastly, current is defined as the movement of electrons in a conductor, which is a fundamental principle of electrical circuits and is critical for understanding how electricity behaves in different materials.
