en.wikipedia.org/wiki/Mains_electricity

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 ?.

Awaiting your reply,

Thanks & Regards,

ANSWER: Electric power by definition is Power = Voltage time Current.  In countries using the higher voltage the product of that voltage times the smaller current consumption gives the same power rating as for the other countries.  There may be some small differences but not significant.

If you check power consumption ratings of appliances for various countries I think you would find them pretty much the same.

I don't see any opportunity in your supposition of different power ratings and consumption charges.  The differences in billing rates from country to country is significant but the power consumed by identical appliances would be very close to identical.

QUESTION: Dear ZZ

Thank you.

Do you still feel for the same model in different countries with different input voltages of 230 V AC, 50 Hz and 110 V AC, 60 Hz for the electrical equipment used, will the electronic meter bill (Units consumed) for 110 V AC will be less as compared to 230 V AC, 50 Hz ?.

There are pros and cons of using 230 V AC, 50 Hz v/s 110 V AC, 60 Hz
adopted as the Power supply standards by different countries ?.

Isn't it ?.

ANSWER: I don't think there is an economic issue here.

Taking a single design appliance with one model equipped for the low voltage systems and the other model for working with the higher voltage system the economy will be nearly the same.  The power consumed will be nearly identical, all other things being equal.  The greater difference is likely the standards needed to meet the countries requirements for safety, usable features and so on that effect power consumption characteristics.  But the motor of a low voltage design will pull about the same power as the high voltage motor because their horsepower rating requirement is essentially the same.

QUESTION: Dear ZZ

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 ?.


Awaiting your reply,

Thanks & Regards,

Answer
Ideally there is little difference in the generating plants of either system.  Optimization in each has reached a high level of efficiency.  

Historically, the 120v system was chosen because it was the best solution for powering the incandescent lamp.  When the European countries came along they chose the higher voltage of 220/230 because of a more efficient transmission line.  Higher voltages are more efficiently distributed due to lower line losses.  In fact, high tenstion lines of many thousands of volts are used for long distance transmission all around the world.

Hope this helps.
