प्रश्न

If air and cloud were good conductors of electricity, do you think lightning could occur? Explain.

थोडक्यात उत्तर

उत्तर

No, there will not be any lightning at all because charge separation cannot take place in conductors. So, all the charges collected at the clouds will continuously transfer through air, i.e. charge will not accumulate on cloud and so, there will be no lightning.
