Why some countries use low voltage but others use high voltage?

You must understand that with higher Voltage you will get lower amounts of current therefore some countries use lower household current applications therefore without diminishing circuit efficiency it is more ideal to up the Voltage
AnswerThe main advantage of using a higher value of a residential voltage is that it enables the use of higher loads.For example, the maximum load for a North American 'receptacle' is 15 x 120 = 1800 W.
The maximum load for a UK 'socket outlet' is 13 x 230 = 2990 W.
Typically, therefore, most UK households use kettles, electric heaters, etc., which are rated around 3 kW -practically double that of the American equivalent.

How old can a child be to child sit?
It depends on where you are. Some countries have legislation for this others do not.
Why do voltage have very high resistance?
Voltage and resistance are distinctly different quantities. I can say some voltages have very low resistances (and high currents), such as when you drop a hair dryer into the tub. You're question as it is written does not make sense.
What are the advantage of high transmission voltage?
Power houses uses high transmission voltage to supply places that are far away from the generation site. When in regards to distance the voltage is primary and the higher the voltage the greater the travel (using appropriate cable sizes etc). This voltage will suffer some loss during trans missioni but will arrive at its destination with a voltage drop that will not greatly affect the point of demand. keep in mind that this transmission is usually converted to Low voltage via a transformer before it is distributed to the end user. Hope that helped:-)
What countries import things from India?
Some countries that import things from India include the United States, China, and Germany. Others countries include Brazil and Singapore.
Why do some countries you the region have generally high standards of living while others do not?
Well because the economy
What education that South America have?
The countries in South America have produced many brilliant scholars over the years. Some countries have an extremely high educational standard - others not so high.
How does the low-voltage circuit controls the power to the high-voltage circuit?
Through a relay or some other kind of high voltage switching device.
Why is there poverty in some countries and not in other countries?
Some countries are richer than others.
When electricity can enter your home from a power station what decreases the voltage to a safe level?
The transformer outside your home reduces the voltage from several thousand volts to around 220-240 volts in your home. In some countries (US and Canada among others) this will be split to 110-120 volts.
Is mains electricity the same in all countries or does it vary?
Voltage varies in different countries; usually the voltage is either 110 or 220 volt. It may even vary within a country; for example, most of Bolivia uses 220 V, but La Paz - the government seat - uses 110 V. Frequency may also vary, being 50 Hz. in some countries, and 60 Hz. in others.
What are the difference between high voltage and low voltage?
Hi, The main difference is Fuel consumption. High current genertors always consumes much fuel because the load on the engine will be high. The high voltage low current generators doesn't need much fuel to run. You can understand this by comparing 1 kva and 5 kva single phase generators. For both generators voltage will be same (230v) But output current differs. So the fuel consumption also differs. But you get a high current source. Low voltage high current generators can be used for welding kind of stuffs which needs high current to do the job. If you have step down transformer then you can save the fuel.
Where in the world do tornadoes form?
Tornadoes can form just about anywhere that gets thunderstorms, though some countries get them more than others. Countries with high numbers of tornadoes include the U.S., Canada, Australia, and Bangladesh.
Why do you write 0 before the decimal point?
That is a convention. In some countries it is customary to include the zero before the decimal point, in others it isn't.That is a convention.

Why are some countries cold?
Cold countries are fr from the equator or at a high altitude.
Do lots of countries have rights?
Yes, all countries have rights. Some have less than others.
