Answer / guest

two bulbs are arranged in series and put in between two
phases............so there is no neutra useing

Answer / karthick

yes because we can light up by using ground

Answer / rakesh iyer

If the voltage between the two phase is equal to the lamp
voltage then the lamp will glow. When the voltage
difference is big it will damage the lamp and when the
difference is smaller the lamp will glow depending on the
type of lamp.

Answer / jacob

yes we can light up bulb with the use of earth because neutral
is taken from earth so this is possible if u have doubt please note the voltage between phase and neutral

Answer / eshwar y p

yes we can do it using two phase lines of 440v.Usually bulb is designed for 230v so by connecting two bulbs in series to get 440v amplitude and then connect this across phase lines the bulb will glow

Answer / p.kamal

usin delta to delta transformer .phase voltage , line
voltage low .ex : one bulb 440 v ry =440 one phase given by
220v .total 440v

Answer / tushar kulkarni

connect two different but same duration angle of phases, and touch both of neutral points of bulbs by hands.
It works!!!!!

Answer / nishant

We can not glow the lamp with earth i experimentaly prove it take a lamp and go towards socket than take one terminal into phase and one into neutral lamp will glow but when one terminal in phase and other is on neutral the lamp will not glow it only happen when 2pahse is available

Answer / abhishek-gaur

m nt sure.... buti thinhk all we need is a potential
difference...

in regular supply... LINE VOLTAGE is of 220v
and there is a neutral... thus a potential difference of 220

if we connect our bulb between a 440v and 220v line, then
also potential difference of 220v is developed

Answer / nilkanth tailor

can anyone tell me instead of bulb. can we glow up tube
light...??

could any one explain me what power factor and where it is use ful
