how to get more than 1000 ohms between 2 earth pits ?

Answer Posted / sanjay d. dabli

Look this is tricky question because earth has resistance from 0 ohms to 10 ohms.This means if we make earth pit we get resistance between 0 to 10 ohms. We can get 1000 ohms resistance between two earth pit by providing 1000 ohm resistance between them.
