Practcally NO, as the earth resistance is usually around 5
ohms in domestic and ind installations and add about 3 ohms
that of Tr neutral earthing.The voltage drop would be
about 80 V in the return path and voltage available for the
appliance would be apprx 150 V with the current dropping to
10 A , for 230 V single Phase supply.Hence it is
possible,if only the earth resistances could be reduced to
very low values

In Indian Household, generally we receive 220V AC single phase supply. But AC has 2 phases, +ve & -ve. So in +ve half cycle current is flowing...so what happens in the -ve half cycle?? Please illustrate.
What will happen if the voltage in my house drops from 220V to any lower voltage?
