Electrical Earthing

We learnt about Earthing.
There are 3 important things to remember
1. Phase
2. Neutral
3. Earthing

What earthing does is that it sends a leakage current back to the ground protecting us from getting harmed.
We measured different places in our Vigyan Ashram using a earth Tester manufactured by "Meggar".
