AC is the abbreviation for which electrical term?

• A. Alternating current
• B. Alternating charge
• C. Absolute current
• D. Analog current

Answer: (A)

The main concept is what AC stands for in electricity. AC stands for alternating current, the type of electrical current that reverses direction periodically rather than flowing in a single direction. This back-and-forth flow is what lets voltage be easily transformed up or down with transformers, which is why power grids and household outlets use AC. The other terms aren’t standard: alternating charge isn’t a recognized description of AC, absolute current isn’t a real electrical term, and analog current isn’t used to describe this phenomenon. In everyday use, you’re dealing with AC at common household frequencies of about 50 or 60 Hz, depending on the region.
