240V is AC (Alternating Current).
Understanding AC and DC
To understand why 240V is AC, it's helpful to quickly understand the differences between AC and DC:
- AC (Alternating Current): The direction of the electric current periodically reverses, creating a wave-like pattern.
- DC (Direct Current): The electric current flows consistently in one direction.
International Standards
The key to the answer lies in global electrical standards. According to the provided reference:
"While Europe would adopt an AC standard of 220-240 volts at 50 Hz, the standard in North America would become 120 volts at 60 Hz."
This statement clearly indicates that the 220-240 volt range, which 240V falls within, is an AC standard. This standard is widely used in many parts of the world, including Europe.
Key Takeaways
Here's a recap of why 240V is AC:
- Global Standard: 240V is aligned with the European AC power standard of 220-240 volts.
- Frequency: AC power is associated with a frequency, like the 50 Hz in Europe, which does not apply to DC.
- Household Power: The power used in most homes and businesses is AC, making 240V AC the norm in regions that use it.
In summary, 240V is specifically designated as an AC voltage, confirming its alternating current nature.
