evidence: Ans. Electronic Voting Machine (EVM) is an electronic device for recording votes. An Electronic Voting Machine consists of two Units - a Control Unit and a Balloting Unit - joined by a five-meter cable. The Control Unit is placed with the Presiding Officer or a Polling Officer and the Balloting Unit is placed inside the voting compartment. Instead of issuing a ballot paper, the Polling Officer in-charge of the Control Unit will release a ballot by pressing the Ballot Button on the Control Unit. This will enable the voter to cast his vote by pressing the blue button on the Balloting Unit against the candidate and symbol of his choice. [...] Q5. What is the maximum number of candidates which EVMs can cater to? Ans. In case of M2 EVMs (2006-10), EVMs can cater to a maximum of 64 candidates including NOTA. There is provision for 16 candidates in a Balloting Unit. If the total number of candidates exceeds 16, more balloting units can be attached (one per 16 candidates) up to a maximum of 64 candidates by connecting 4 Balloting Units. However, in case of M3 EVMs (Post 2013), EVMs can cater to a maximum of 384 candidates including NOTA by connecting 24 Balloting Units.
