Please define ampere?
it is in our knowledge tht right plug of supply of residential suppy system is phase n other is neutral...howevr the battery charger of mobile works in both ways...i mean it is not restricted in only one direction.ny of the holder of charger can hav phase .so y is it not lik tht phase of supply must b connected 2 phase of charger...?
