The 220V system is newer than the 110V system. One reason why the U.S. is still using it is because they already laid down the infrastructure for 110V system when the 220V system came out. It would have been too costly to switch to another system and impractical to have 110V and 220V systems in one country.
Yong electric comsumption nung isang electrical unit nakadepende
sa power rating nung unit mismo (ie. kung ilang watts yong na-c-consume/hour).
I would say, mas mapapamahal ka pa nga kung yong unit na gagamitin mo sa pinas is 110V compared to a 220V unit with the
same specs because you will be using a transformer for the 110V unit. I think the transformer itself comsumes some electricity even
without plugging any electrical unit on it.

sa Saudi lang meron to please both americans and british.
220V and 110V consumes about the same amount of power since the 110V applicance will consume twice as much CURRENT as compared to a 220V version of the same appliance.
But, the 220v version will be "safer" because it will need less current, hence making the wiring "cooler". The more current running thru a wire will generate more heat.
1. 220 V needs smaller wires than 110V since wires are sized according to current carrying capacities - that is for first cost of wiring installation.
2. Line losses (heat produces on the wires/conductors) on 220 is about a quarter of 110V (theoritically a quarter) when using the same wire. That is why higher voltages are used on transmission lines.
The main consideration of using 110V is safety. It safer to be in contact with a 110 V line than with 220 V.
RedHorse ... ito ang gusto mong i-type ... P = (I^2)R
the character "^" is commonly used to mean "to the power of" for mathematical expressions
nickbay is right about "I would say, mas mapapamahal ka pa nga kung yong unit na gagamitin mo sa pinas is 110V compared to a 220V unit with the same specs because you will be using a transformer for the 110V unit.

and of course transformer losses will also increase as the load increases
btw.. mas mataas voltage... mas konti power loss pag dumadaan sa wires... thats the reason may high voltages tension wires and substations.. para yung travel sa wire ng koryente to us mas konti yung loss
sa amin, (angeles city) 110v and 220v ang gamit namin...... ang pangit lang sa 110v na appliance, lik yung galing japan fopr ex, pag nsaksak mo ng 220v, masisira....

di ba usually yung mga plug ng 110v appliances is bilog? para hindi mo masaksak sa flat 220v outlet.

oo nga dito sa Angeles city... 110v and 220v... di naman pangit gamit sa japan problem lang 100 v lang sila and kung 110v gamit mo medyo mainit siya kasi sobra ng 10v kung minsan nga 120v pa ang lumalabas sa meter pag tinitignan ko koryente dito hehehhe.. kailangan talaga ng transformer na me 100v pag galing sa japan just my two cent
