why battery dc voltage become Half when we check with
respect to ground for example 120volts + and - terminals
and when we check + terminal with Earth thats 60volts why
60volts we can not ground the battery.

Answer Posted / k.prakashchandra

The above answer is correct.If you use an earth fault
indicator ,you are able to measure voltages. And if you run
both leads along the ground or a metal surface ,you can
measure voltages with a digital voltmeter ,as the
capacitances between the leads and the surface/ground, bring
the surface/ground to +or- zero potential.
