It insults my intelligence when we. Quote and use US systems as a guide for a 3rd world nation like Nigeria. States structure in US is totally different from the way ours are constituted. Their states are not based on ethnicity but Nigerian states are. So, stop all these importation of ideas that go no where. In that case why don’t we just bring electronics from US which is 110V and just plug into Nigerian power system of 220/240V without using any voltage adapter. Is not automatic explosion? I beg bring your minds down here so as to function well.
