Through the State elections you are electing the Members of the State Legislature who will represent your constituency at the state level. The State Legislature might have an Vidhan Parishad (Upper House) or not, but it always has the Vidhan Sabha (Lower House).
Each member of Lower House of a state is elected for 5 years, and each member of Upper House is elected for 6 years.
The number of members of the State Legislature varies across states, depending upon the population in that state. For example, the State Legislature of Uttar Pradesh has a considerably greater number of members than Pudcherry.
