Why dont we get shock while testing for voltage with a line
tester?
How the bulb inside the tester glows while testing with
tester coz we are totaly isolated from earth or we are not
giving close path for the current to flow?

Answer Posted / phaseneutral

Neon line tester has a high value resistor inside. It protecting you from electric shock.
