Answer Posted / kannan
there is a ballast resistor which is connected in series
with the testing terminal and the neon lamp, this limits
the current flow to the neon lamp, there to body & ground.
this is the one which protect you from electric shock. but
you cannot go on using the tester for any voltage. there is
voltage limitation, normally around few hundred volt, above
which you can get a shock.
