    Question What are the advantages and disadvantages of a 220V 50 Hz & 110V 60 Hz environment

    Here in India we have a 220V 50 Hz electricity distribution and there in US and in several other countries exists a 110V 60 Hz electricity distribution.

    My questions are -

    1.What exactly are the advantages and disadvantages of the two environments?

    2.What possibly are or were the practical reasons behind the various countries for opting for a particular environment.

    3.Can the two environment be compared with a conclusion - Environmnet X is Superior to environmet Y .


    4.Why was the figure 110 and 220 only chosen and amazingly one is just the double of the other in magnitude ( though not in frequency) .Why weren't any other voltages chosen .How was it decided that this particular amplitude of voltage would serve the exact purpose and not any other voltage and then the equipments were designed / manufactured accordingly.

    5.Is frequency of AC a function of the voltage viz 60 Hz corresponds to 110V and 50 Hz corresponds to 220Volts .Is there a mathematical relation between the frequency and the voltage , if yes what's the formula.

    6.Which of the two systems is more efficient / competent in any way say in monetary terms / cost of design/manufacture and implementation et al .


    I am just trying to seek an answer to a question which I have been asking my teachers since I was a kid and till now no body has given me a satisfactory answer.I don't intend to make a derogatory comparison .

    Incase this question is beyond the scope / spectrum of the site , then may I please request very humbly for the forum member to give me some relevant links which precisesly and explicitly explain the above facts.

    Thanks and regards

    I would suggest to ask this question at badcaps.net, may be there are some genius, who can answer all your questions.

    Generally, i would say the 220v system is more efficient, regarding power delivery and losses.
    But this comes at the price of better isolation requirements and the higher lethal risk if something is going wrong.
    This is caused by the ohms law, (I=U/R) which means that at 220v the lethal current is more easily reached then with 110v.

    Frequency is choose for the intended consumer. Not that i can tell you much about the details, but for very big motors (e.g. electric locomotive) a far lower frequency is used (16,70 Hz in DE, CH and AU).
    I think that the figures are chosen due to material and physical limits at the beginning of the electric age.
    Then they are kept to be compatible.

    220V

    * less current for the same power, so less heating (PC power supplies are more efficient at 220V)
    * more dangerous

    Here is what I wrote for the following Quora question
    "American has 120v and UK has 240v. Is there any advantages to 120v and vice versa?"

    America has 220v; there is a 220v circuit in most American houses for the high consumption devices (clothes dryer, range etc.)
    HOWEVER
    There is one terrible disadvantage to the way 110v is often implemented in America, namely through a neutral line that divides the 220v into two circuits of 110v. Some devices in the house are on one circuit, some on the other. Now the problem: if that dividing neutral should ever fail due to a bad connection then some devices can be exposed to more than 110v and destroyed (it is almost paradoxical that the loss of a connection can lead to higher voltage).
    To be explicit, have a washing machine on one circuit and a PC on the other; disconnect the dividing neutral and the 220v now goes across the two devices in series and the voltage is now unevenly distributed across them.
    The following video illustrates it better than I can
