why does not tester light up when it is touched to neutral of 3 pin socket...

Answer / ankamsreekar

The practical line testers are works for the voltages above
150v. The return path is earth (land surface) via human body.

When you touched to line the voltage across the tester is
230v. If you touched to neutral the voltage across the
tester is in order of 2-10V depending up on the conditions
of distribution transformer.

so the tester will not work.

Answer / jaswinder singh

Tester always lights up due to potential difference between
phase and earth. Neutral is at zero potential from earth so
the tester does not glow.

Answer / k.prakashchandra

I gave the wrong answer as the word 'not' escaped my
notice..The tester requires at least 40-60 volts to light
up depending upon the series resistor used.As neutral is at
almost zero potential from ground ,tester does not light up.
