Question

When a positively charged conductor is earthed then?

Answer 1

As we know that in normal current flow, electrons passage is always from the negative to positive side , now in the case of earth it acts as a ground to the positive charge, and current flows from positive charge to the earth, which acts as a anode and as we know a passage of current occurs only if there is negatively charge electron flowing towards positively charged cathodes. So electrons may flow from earth neutralizing the positive charge
