In 2009 Lok Sabha elections, the state recorded over 48.46 percent voter turnout.
Reports of problems in EVMs came in from some districts, where the machines were repaired or changed.
Earlier in the morning, polling started amid tight vigil by security forces.
"The voting began at 7 a.m. at over 38,220 polling stations spread in these 20 constituencies. We have made elaborate security arrangements for peaceful polls," an election official here told IANS.
In all, over 80,000 security personnel have been deployed.
The political fate of 239 candidates is being decided Thursday.
Among these are Sachin Pilot, C.P. Joshi, Girja Vyas, Chandresh Kumari and Jitendra Singh of the Congress, and Sanwar Lal Jat, a minister in Vasundhara Raje government, and Olympic silver-medalist shooter Rajyavardhan Singh Rathore of the BJP, and Jaswant Singh and Buta Singh who are contesting as Independents.
The Congress and the BJP are fighting for all 20 seats, while the Aam Aami Party is contesting 17, and the Bahujan Samaj Party 18 seats.
The state is witnessing a keen tussle between the BJP and the Congress. In the last Lok Sabha polls, the Congress won 20 seats and the Bharatiya Janata Party four, and one seat was won by an Independent.
It has normally been a two-party contest in the state.
This time, however, the AAP and Mayawati's BSP are trying to make a dent in the vote banks of both the major parties.
While during campaigning the Congress raised the issue of development, the BJP spoke about corruption and bad governance.
The BJP also targeted the United Progressive Alliance government at the centre on price-rise and its inability to curb corruption.
Chief Minister Vasundhara Raje, and BJP's state unit president Ashok Parnami were among the first to cast their votes THursday morning.
"We are sure of winning all 25 seats," said Raje after casting her vote.
Parnami said the people are voting for the BJP this time as they are fed up with bad governance of the UPA government.
