Answer / sanjayjssate

the ground has always zero voltage with zero resistance, so if we connect any voltage it will draw huge current. But neutral has some resistance which balance the current flow .

Answer / ananda kumar barik

If we use ground at neutral it make unbalance load at distribution transformer which increase the voltage depending g the load .Low load has high voltage & high load has low voltage

Answer / k.prakashchandra

Earth resistance can not be made as low as that of conductor economically .

can we use ac ameter as dc ameter with ct

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
