Why does a 220V supply current flows through the Ground(i mean Earth), whereas when i connect a 12V battery and a small LED/bulb to it and the other terminal to ground(earth), why won't the bulb glow? My question here is: If it is possible to glow a 220V rated bulb by connecting it b/w phase and ground, why is it not possible to glow a bulb(rated 12v) b/w positive of a battery and ground?
