In a three phase transformer(delta/star connected)when i
touch one end of the bulb in any one phase and other end to
earth..will the bulb glow or not..if not why?..i'm touching
the bulb in star connected side...
Answer Posted / bala123
Definetely the Bulb will glow,because essential points for
glow the lamp can get via your body i.e phase and
neutral,hence the lamp will glow.Incase if not,i think (not
sure) your body may have higher ohmic resistace.
