# Components for Building Computers From Scratch/Mains Electricity by Country.

Some Countries supply the Alternating current (AC) Electric Power supply with Input Voltage rating as 230 V, 50 Hz and some Countries supply Alternating current (AC) Electric Power supply with Input Voltage rating as 110 V, 60 Hz.

So similarly various Electrical appliances and devices viz Microwave Ovens, Geysers, Electric Iron, freeze, Television set, Fans etc are designed to work with this Input Electric power.

Do you feel people residing in those countries which supply the 110 V, 60 Hz Input Power supply will have electricity Meter rating i.e. Electricity Bill less (i.e. Power consumption - Watts) as compared to those people residing in countries which supply the 230 V, 50 Hz Input Power supply ?.

Electricity Bill - Meter reading will be less for consumers staying in those countries which supply 110 V, 60 Hz than for those consumers staying in those countries which supply 230 V, 50 Hz electric supply ?.

Does the Input Electric Power variant will make a difference in Output power consumption and subsequently in Electricity Meter reading ?.

ANSWER: In the US we have both. I would say you would need to contact the electrical company where you live to find this out.

QUESTION: Dear Keith

Thank you.

One Last Question.

Do you feel those countries which supply the 230 V , 50 Hz Input Power Supply through Power transmitting stations (MW) i.e Power Plants overall results in more cost factor for production (Generators equipment) and maintenance than those Power plants which generate 110 V, 60 Hz for distributing electricity to factories, Household etc.

i.e. To Summarize my query, Do those Power plants (where countries use
230 V AC, 50 Hz) can result in Overall more cost factor for running the Plant than those Power Plants (where countries use 110 V AC, 60 Hz) ?.

i.e. Production and maintenance cost for Power Pants increases in those countries (230 V Ac, 50 Hz) than countries (110 V AC, 60 Hz) or it should not ideally make any difference ?.

I am certainly not very knowledgeable about electricity. I have more low voltage than high voltage experience. However, I do think that it does not matter what voltage the power plant is putting out when it comes to expense. There are factors like; 230V AC running some sort of appliance for 30 minutes and another appliance running 24/7 on 110V. Which one uses more electricity? With my limited knowledge, I would say the answer is according to what kind of appliance it was running and the power consumption of the appliance. You see.....there are just so many variables there. I wish I could give you a better answer but my knowledge of high voltage electricity is limited.
