It might not mean something but volts is what we pay the electricity bill for
kwatts gets converted to volts in meter reading.
the normal current supply to homes is ac
the current pay would be 13440 dollars for a month
Wut? Where on earth is that? Normal supply is ac (depends on what psu you are using)

India is 240V same as the Brits who first installed it there......
Yes, that's my experience, but a search of the infallible Google reveals that dc supply is available, also it's where the poster tharani comes from. What do you mean by poster. ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) ? omg i get it you mean one who posts on bitcoin talk forum is a poster . lol

Wut? Where on earth is that? Caravan site? ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Apparently the answer is India. You learn something every day...... India is 240V AC same as the Brits who first installed it there...... now its ac ( depends upon what psu you are using for the miner )

Caravan site? ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) A normal residential household consumption will have ac supply in india (all calculations above are for dc as per the psu you are using values may differ for ac) i don't think a single caravan would charge 440 volts for 2 months ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) lol Also a even a bunch of caravans won't have huge consumption even if they had air conditioner and some electrical appliances. It's funny that you think it is a caravan site .

Brits installed it 67 years ago or maybe even before 80 years
it's been more than 69 years after we got independence and have our own democracy and gov
now its dc
its not a new fact it has been the system for years' apparently you don't try to get to know facts about other countries cause you don't need it as a necessity.
Mostly people here would be from the us , uk and the europe
Whoa slow down. FACT: every visit I have made to India (many), I have used AC in hotels, offices, shops, beach bars etc. India has an AC grid BUT there is a perfectly legit way of receiving DC to your home there but yes, it will be off grid supply unless inverted (like a caravan) ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Lighten up guys.

I don't know a well knowledged friend told me it was dc next time i pay the electricity bills i will ask the board .
Yeah sometimes i take the card and go to pay in the office .
well Digitalbitcoin (bitcointalkmember)
told it was ac for homes and dc for industry.

This is industrial ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fshowroom.ecoxpert.schneider-electric.com%2Fuploads%2Fimages%2Ffactory.png&t=665&c=nw31de1zSDjzzw) This is commercial ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fwww.wanderingearl.com%2Fwp-content%2Fuploads%2F2012%2F12%2FBeach-Huts-on-Palolem-Beach-Goa.jpg&t=665&c=qnKWL36DKSC4PA)

IMPORTANT UPDATE
IT IS AC FOR RESIDENTIAL
DC FOR INDUSTRY
If commercial supply comes under residential it is ac then
IT IS AC
FINAL
SUPPLY UNTIL TO THE PLUGPOINT FOR RESIDENTIAL IS AC
DIFFERS UPON THE POWER SUPPLY UNIT YOU ARE USING .
OK GOT IT .!!!!!!!!!!!!!!!!!!!
NO CONFUSION
The overenthusiastic friend of mine had calculated according to usage of ups he does not know much about psu's or miner's
he says that the current supply will be ac until plug point and when it reaches some devices the adapter converts it to dc.
So he thought the input was in dc which i clarified it with him today.
SO UNTIL PLUGPOINT IT IS AC

Fine. AC, DC, whatever. To makes things easy, let's use water as an analogy to electricity: For water the amount of force it has is measured in PSI, kPa, whatever. For electricity the amount of force is Volts. A quantity of water is gallons, liters, drams. A quantity of electricity is Amps.
Now comes where the confusions seems to be: The amount of WORK the volts and amps together produce. The unit for that is Watts or Joules and has a simple formula. Watts = Volts x Amps and the rate of use is Watts/time
Everywhere except apparently India the electric bill of all consumers be they residential or industrial is based on Watts - from an AC source - consumed. For most loads this will more or less be a constant value regardless of what the line voltage does because generally if the line goes low the load will try to pull more amps to keep power constant (for motors and non-incandescent lighting).

... DC does not travel well over distance ...
Your statement is simply not true. The power loss experienced due to long distance power transmission is less for DC than it is for AC. The issue is that DC is typically harder to convert to higher or lower voltages. DC voltage conversion is also traditionally more expensive, but there have been recent advances that should bring the costs down. There are other considerations in the AC vs DC war with regard to basic electrical theory, but we are already quite off-topic. I suggest that folks interested in learning about AC vs DC power transmission read the article in the link below as it explains some of the basic pros and cons. http://www.theenergycollective.com/roger_rethinker/204396/ac-versus-dc-powerlines

i just wanna know the correct current costs for antminer s9 for 24 hours for ac single phase and three phase i don't know correct power factor. also i don't know the amps calculator here http://www.rapidtables.com/calc/electric/kw-to-volt-calculator.htmAlso i am asking you guys to tell how much a antminer s9 is gonna produce in a day.

i just wanna know the correct current costs
for ac single phase
i don't know correct factor.
My s9's each pull around 1,300w. From a 208VAC line each pulls 6.25 Amps. The PSU's for these are small enough that they are all single-phase. 1 or 3-phase only matters in regards to what the utility charges you. In urban areas a general rule of thumb is that if it is a commercial/industrial user and they require more than around 50kw it will generally be 3-phase power supplied.

Extremely sorry guys for saying power supply is dc power supply in india is ac
also i will double clarify before having posted on here.not from just getting info from a oversmart/overenthusiastic person.

It has nothing to do with this discussion and is generally always assumed to be a value of 1, For acedemic and nit-pickers however most good PSU's have a PF of around 0.9 Dude (or dudette) - read up on basic Ohms's (for DC) and Watt's (for AC) Laws
