Using the tester is similar to open loop circuit used by the railways to run electric trains. There is only one line above the train touched by the pantograph and after passing through the motors the circuit ends by touching the rails (thandavalam) which acts as the ground. But while testing the current involved is very small and our body (we have plenty of water and blood) conducts it to the ground. If you wear completely insulated footwear you will see the tester will not light up. The household neutral is grounded either at the transformers near your house or at the nearest distribution station completing the circuit.
The amount of Current shock and one dying out of it is dependent both on the potential difference (Volts) and the current (Amps) and also which part of the body it passes. If it is thru heart death is definite unless someone use a defibrillator to start the heart immediately after the accident if it is household current. Lightening (minnal and idi)strikes are fatal because the voltage is several million. The American voltage supply is 110V and is less lethal than ours which is 230 V. Farmers get heavy shock and die because their high power pumps are 440V. Performing electrical work alone is never suggested for safety reasons.
நீண்ட நாள் சந்தேகம் தீர்ந்தது மிக்க நன்றி நண்பா
Yes
Very short time much knowledge ....I wish to learn electronics repair online bro
1 Mega ohm 1 Lac ohm illa bro
1 Mega ohm=10 Lac ohm.. But Otherwise video clear very useful
You are correct and he made another mistake with current. 22 mA instead of 2.2 mA.

நல்ல வீடியோ தம்பி ரொம்ப நன்றி தம்பி புரியும்படி சொன்னதுக்கு
உங்களது கருத்தை பதிவிட்டமைக்கு நன்றி அண்ணா 🙏.
Very useful thank sir and which metal used metal rod , why using spring connector
Bro one doubt
When I wear a shoe that time how is possible to get neutral

I do get a mild tingling current while testing. But it is negligible effect.

sir 1Megaohm equal to 1000000 ohms.not 100000 ohms ila
Best .... Bro

Hi bro..
1 mega ohm = 1000000ohm
220/10^6 = 220mA
Thanks for your correction.
220÷1000 000= 0.00022 A
0.00022×1000= 0.22 mA
200 milli Amps is a lot of Current enough to give you a jolt. Anyways it is 220 micro Amps.
Thanks

Mega ohm =10⁶

0.00022×1000= 0.22 mA
