What is AC and DC current?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
DC (Direct Current) flows in one constant direction, like water through a pipe in one direction. Batteries provide DC. AC (Alternating Current) periodically reverses direction, typically 50-60 times per second (Hz). Wall outlets provide AC. Both follow Ohm's Law, though AC circuits involve additional considerations like impedance.
