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 / deepak

inside the tester their is a resistor which limits the current flowing through it hence we dont get shock. n we touch the finger only for complete the ckt.
