Consider the following statements: 1. The voltage developed across the OFF switches of the half-bridge converter is the maximum dc-link voltage. 2. In the full-bridge converter, the voltage across the primary of the transformer is the dc link voltage. 3. The voltage developed across the OFF switches of the full-bridge converter is half the maximum dc-link voltage. Which of the above statements are correct?
Which of the following power station is situated in Madhya Pradesh state? Satpura Thermal Power Station Shree Singaji Thermal Power Station Sanjay Gandhi Thermal Power Station Amarkantak Thermal Power Station
There is only one rail track between stations A and B on a railway line. One hour after the northbound superfast train N leaves station A for station B, the southbound passenger train S reaches station A from station B. The speed of superfast train is twice that of express train E, while the speed of passenger train S is half of that of train E. On some one day train N leaves from station A to station B 20 minutes late than its usual schedule. Both Train N and Train S have increased their speed to maintain the schedule as per the table. If the superfast train doubles its speed, then what should be the ratio (approximately) of the speed of the passenger train to the speed of the superfast train so that the passenger train reaches the station on that day at the exact scheduled time.

Consider the following three statements about link state and distance vector routing protocols, for a large network with 500 network nodes and 4000 links. [S1] The computational overhead in link state protocols is higher than in distance vector protocols. [S2] A distance vector protocol (with split horizon) avoids persistent routing loops, but not a link state protocol. [S3] After a topology change, a link state protocol will converge faster than a distance vector protocol. Which one of the following is correct about S1, S2, and S3?
