Q- What was the impact of electricity on the system of irrigation?
Answer:- at earlier time people use Persian wheel to fetch water from wells and irrigate their fields but at that time they use small fields because they are unable to irrigate big fields with the help of Persian wheel but after the supply of electricity they start using tube wells due to which now they are able to irrigate large fields and also they get large amount of good crop from which they are able to earn much.
