Explanation:

The Lok Sabha is directly elected by the people. For the purpose of elections, the entire country (State, in case of State Legislative Assembly) is divided into territorial constituencies of roughly equal population. One representative is elected from each constituency through universal adult suffrage, where the value of vote of every individual would be equal. At present, there are 543 constituencies. This number has not changed since the 1971 census. The Lok Sabha is elected for a maximum period of five years. Before the completion of five years, the Lok Sabha can be dissolved if no party or coalition can form the government or if the Prime Minister advises the President to dissolve the Lok Sabha and hold fresh elections.
