is 240v ac or dc Page 18

Ah, the timeless question of 240 volts: AC or DC? In Australia, your standard wall socket delivers 240 volts AC (alternating current). This means the current flips direction 50 times a second, which is far more practical and efficient for power distribution than its one-way cousin, DC (direct current). DC is more common in batteries, electronics, and some specialised industrial setups, but the mains is almost always AC. So, unless you’re charging a dodgy old laptop or a fancy electric car, you’re dealing with AC.
