What country had electricity first?

These were invented by Joseph Swan in 1878 in Britain and by Thomas Edison in 1879 in the US.

Edison began commercial production of carbon filament bulbs in 1880.

Which is safer AC or DC?

An electric shock has the capacity to induce ventricular fibrillation which can lead to heart failure and death. Avoiding any form of electric shock is preferable, but DC is considered safer in these circumstances as the human body’s threshold to DC is considerably higher than to AC.

Why is DC current not used in homes?

Direct current is not used at home because for the same value of the voltage, DC is more lethal than AC since direct current does not go through zero. Electrolytic corrosion is more an issue with direct current. DC inductors are more complicated. It requires commutators, electronic switches and brushes.
