IF THE VOLTAGE BETWEEN THE TWO PHASE IS EQUAL TO LAMP VOLT
IT WILL GLOW
BUT IF IT IS BIGGER IT WILL DAMAGE
IF THE VOLT LESS THE LAMP GLOWING WILL DEPEND ON THE TYPE OF
THE LAMP

Answer / arif

iamp rating is 440v the lamp will glow ,

Answer / shubham

Assuming a general situation without any rating problems(
becoz like this many problems would be there)..and lamp
means a general incandescent lamp..
for all those moments when there is a voltage difference
between the two phases the lamp will glow with output lux
proportional to the magnitude of voltage difference.i.e.
what we are going to see is a sinusoidal variation in output
lux of the bulb. i.e. from 0lux to maximum then again to
zero and so on
that's it

Answer / umar kamboh

Suppose a bulb operate at 415 volts. And there is three phase system (three phases have same voltage magnitude but 120 degree apart). The line-line voltage b/w any two phases is 415 volts (two phases have same magnitude but they will be 120 degree apart i.e 0,120 or -120).. ..The current b/w two point flow either when there is potential difference or there is phase difference (even when voltage magnitude is same).In our case (Bulb with two phases) second condition is full-filled.Hence the bulb will glow and then become dark and then glow (i.e it will blink).but remain glow for long time and will become dark for a small time (as compare to glow timing).

Answer / am12

it will we glow koyki one phase will connected wit lemp fist solt and 2nd phase will connected with 2nd solt so we know that there will current will flow same in both phase but very small difflection in any phase that phase is working as a nutle and lemp will glow but there very loss of electricl energy

Answer / alok

If phase to phase voltage is up to the thersold voltage of Lamp it will glow, A voltage greater than thersold voltage will damage the Lamp

Answer / vinay

Moastly lamp is operat in 230v.

we are connected lamp in 2-phase so lamp across voltage is
440v so lamp is build up.& not glow

it will not glow it gets phase to phase n the lamp will
fuse

IN THE CASE OF AN ELCB, IF THERE IS ANY UNSTABILITY BETWEEN PHASE AND NEUTRAL IT MAY TRIP. BUT MY QUESTION IS WHEN A LOAD IS CONNECTED IN BETWEEN P AND N, THE LOAD CONSUMES SOME POWER AND THERE IS A DIFFERENCE IN NEUTRAL WITH RESPECT TO THE PHASE. THUS ACCORDING TO ME, THE ELCB WILL AUTOMATICALLY OPERATES WHEN EVER THE LOAD CONSUMES-- I KNOW IT IS WRONG. BUT THE SOLUTION IS?????????
