Answer / virendra joshi

Basic rule of electricity is W= V*I now wattage would be
the rating of the quipment which remain constant means the
voltage is decrease then current will increase but if
frequency is increase current will decrease now as per this
in foreign the frequency is increase & voltage is decrease
so the required insulation level is decrease. in india the
voltage level is 230 & frequency 50.

Answer / muhammad ashraf

In forign countries, they use 200V in three phae at 60 HZ
and according to the principal of electrical theory in star
connection phase voltages are under root 3 time less then
line voltages, and for domestic control we use star
connection, this the reason that in India and Pakistan we
use 415V three phase supply and according to the formula
single phase voltages will be 230, and according to this
standard our home appliances are design at 230 volts. And
forigner use 200V three phase supply And according to the
formula thier single phase voltages are 110V. And thier
design of home applinces are 110V.

Answer / elangkumanan

forign side all home appliance material volt 110v but
indian appliance volt 220volt that is a difference
another forign transformer step down volt default use
110v but inian system volt 230 volt that is different
