Today the quality of the earth in homes that are normally electrically grounded is being tested. The 100 W filament bulb burns in good light both phase and neutral, but in very low light with phase and earth. From this it can be seen that the way this earth is done is not correct. Deeper earthing is required for this. This is shown in detail in the next video. Very strong earthing is required to solve the earth leakage problem of the house. The 100W bulb will burn in the same light in both modes.
