Answer / muthukumar

In other end we have the resistor for current limiting

Answer / kalolia alap r

in the tester rated 230v,and suppose resistance of tester in
megaohms,so the current will be less than 5 mA,it create no
hazard to human body,sowe don't get shock...

Answer / rajeev.p

The other end of the tester,supply came through a
resister.There for the voltage is reduced by resistor.

Answer / nethaji

Because in other end resistor connect with series

Answer / nethaji

Resistor

Answer / shashidhara

Rating of voltage is 230V only. The current is low enough not to hurt us and just enough to light up the bulb. But, the same tester can't be used to check higher voltages. We use only the voltmeters and other devices to check supply in higher voltages. If we use tester, we get shock at those high voltages.

Answer / yogesh raste

Since our body resistance is very high we do not expeince a
shock.

what is the necessary of using inductance property in transmission lines even through resistance is used to opposes the high current flows in that?????
