Discussion Overview

The discussion revolves around the question of how much electricity is needed for a device that requires a 220 V supply. Participants explore the implications of voltage requirements, the meaning of "electricity," and the vagueness of the original question. The conversation touches on theoretical and practical aspects of electrical supply and device operation.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants assert that if a device is rated for 220 V, then that is the necessary supply voltage, and it may work with slightly lower voltages but risks damage with significantly higher voltages.
  • Others argue that the term "electricity" is vague and question what the original poster is specifically trying to understand, suggesting a need for clarity regarding energy, power, current, or voltage.
  • One participant humorously suggests that using about 24 nine-volt batteries could approximate 220 V, though this is noted as impractical for real applications.
  • There is a mention of communication issues, particularly regarding the original poster's phrasing and the need for clearer expression.

Areas of Agreement / Disagreement

Participants generally agree that the original question is vague and requires clarification. However, there is no consensus on the interpretation of "electricity" or the specifics of what is needed for the device in question.

Contextual Notes

The discussion highlights limitations in the original question's clarity and the ambiguity surrounding the term "electricity," which may depend on the context of energy, power, current, or voltage.

If you have a device which is rated for use with a 220v supply, than that is the supply voltage you need.
It will probably still work with a slightly lower supply voltage, but a significantly higher voltage is likely to cause components to break down.

"Electricity" is a meaningless term. If you need 220 volts to power a device, then you must find a power source that provides 220 volts. What exactly are you trying to do?

Note that your post falls dangerously close to being substandard, so please put a bit more effort into explaining things and making your posts understandable. If English isn't your first language then you may want to get someone to help you.

Yes this certainly is a very vague question. I could say that about 24 nine volt batteries such as used in a smoke detector will get you pretty close to 220. It satisfied the question yet is quite likely impractical for anything useful.

i just try to clear my confusion. that's why i asked it. thanks for your answer.
And English is not my first language . But I can write and speak English well . thanks again

What we have here is a failure to communicate. It centers around the term 'electricity'

electricity

noun elec·tric·i·ty \i-ˌlek-ˈtri-sə-tē, ē-ˌ, -ˈtris-tē\
Popularity: Top 20% of words ( << i guess a lot of people look up its meaning! - jh)
Simple Definition of electricity
  • : a form of energy that is carried through wires and is used to operate machines, lights, etc.
  • : electric current or power

Does your confusion relate to energy, power, current or voltage ?

oh. Thanks Dave.
I thought his posts might be a bit dismissive, but I'm slow to catch on.

Thanks !

Most members who have been banned are still able to login and read the forums, and send and receive some PMs, they just cannot post.

Apparently.

AC? And how long does he want to run his device for?
