Answer Posted / mir jahan
Third world countries like India, Pakistan etc, due to
extreme poverty, they cannot afford power lose. so we use
220 volts/50hz while in Advanced countries, money is not an
issue. Therefore, they use 110 as a safety measure.
As, power out put= (square of current)(voltage)
Decreasing of voltage increases the current and power loss
is square of the factor.
