What is electric current defined as?

a flow of electricity through a conductor
removing superfluous or unwanted hair by passing an electric current through the hair root
an artifact that is one of the individual parts of which a composite entity is made up
an animal organism in the early stages of growth and differentiation

The correct answer is: a flow of electricity through a conductor

The definition of electric current as the flow of electricity through a conductor is foundational to understanding how electric circuits operate. Electric current refers to the movement of electric charge, typically through a wire or other conductive material. This flow is driven by the difference in electric potential, similar to how water flows through a pipe due to pressure differences. Currents can be measured in amperes (A), and they are essential for powering devices, conducting signals, and executing various electrical applications. The strong association of this definition with electrical principles makes it the most accurate choice in this context, aligning perfectly with the core concepts of electricity and electronics.
