When we compare the half bridge converter and full bridge converter 1. The maximum collector current of a full bridge is only double that of the half bridge 2. Full bridge uses 4-power switches instead of 2, as in the double bridge. 3. Output power of a full bridge is twice that of a half bridge with the same input voltage and current. When of the above statements are correct?
Match List I (Bridges) with List – II (Quantity measured) and select the correct answer using the codes given below the lists: List - I List - II A. Anderson Bridge i. Frequency B. Kelvin Double Bridge ii. Resistance C. Schering Bridge iii. Inductance D. Wien Bridge iv. Capacitance
Four friends A, B, C and D need to cross a bridge. A maximum two persons can cross it at a time. It is night and they just have one lamp. Persons that cross the bridge must carry the lamp to find the way. A pair must walk together at the speed of slower person. After crossing the bridge, the person having faster speed in the pair will return with the lamp each time to accompany another person in the group. Finally, the lamp has to be returned at the original place and the person who returns the lamp has to cross the bridge again without lamp. To cross the bridge, the time taken by them is as follows: A :1 minute, B : 2 minutes, C : 7 minutes and D : 10 minutes. What is the total minimum time required by all the friends to cross the bridge?
A boat is on the one side of a bridge and the other boat is on the other side of the bridge. The bridge is 36 meter above the river surface. The angles of depression of both the boats from the bridge point on the bridge are complementary to each other and the angle of depression of first boat from the bridge is tan-1(1/3), then what is the distance between both the boats?
A cow was standing on a bridge, 5m away from the middle of the bridge. A train was coming towards the bridge from the ends nearest to the cow. Seeing this cow ran towards the the train and managed to escape when the train was 2m away from bridge. If it had run in the opposite direction, it would hit by the train 2m before the end of the bridge. What is the lenght of the bridge in meters assuming the speed of the train is 4 times that of cow ?
World Bank has employed major dimensions to construct measures of governance. These dimensions are:
1. Voice and Accountability - measuring political, civil and human rights
2. Instability an d violence - measuring the likelihood of violent threats to or changes in government, including terrorism
3. Government effectiveness - measuring the competence of the bureaucracy and the quality of public service delivery
4. Regulatory burden - measuring the incidence of market, unfriendly policies
5. Rule of law - measuring the quality of contract enforcement, the police, and the courts, as well as the likelihood of crime and violence

Consider the following statements related to oscillator circuits : 1. The tank circuit of a Hartley oscillator is made up of a tapped capacitor and a common inductor. 2. The tank circuit of a Colpitts oscillator is made up of a tapped capacitor and a common oscillator. 3. The Wien Bridge oscillator is essentially a two-stage amplifier with an RC bridge in the first stage, and, the second stage serving as an inverter. 4. Crystal oscillators are fixed frequency oscillators with a high Q-factor.  Which of the following are true?
For any Wien Bridge oscillator, R1 = R2 and C1 = C2 always in the bridge, provided the phase shift through the amplifier is zero.
In a Wien bridge oscillator, it is found that at the frequency ωO there is no phase shift in RF/R gain loop and the phase shift of the amplifier is also zero. Then what is the equation for the radian frequency, given R1, C1 is the series network of bridge and R2, C2 is the parallel network?
