Which statement defines current?

Which statement defines current?

• A. Electrical pressure pushing current
• B. Flow of electricity measured in amps
• C. Alternating current changes direction
• D. Direct current flows one direction

Answer: (B)

Current is the flow of electric charges through a conductor. It tells you how much charge passes a point each second, and it is measured in amperes. This is why describing current as the flow of electricity measured in amps is the best definition. Voltage acts as the push that drives charges, and resistance determines how easily they flow, with Ohm’s law linking them as I = V/R. The statements about alternating current and direct current describe the direction behavior of the flow in different systems, not what current itself is, whereas the flow in amperes captures the essence of current.
