A 3-phase bridge rectifier charges a 240 V battery. The rectifier is given a 3-phase, 230 V supply. The current limiting resistance in series with the battery is of 8 Ω. Find the average value of battery charging current.

A 3-phase bridge rectifier charges a 240 V battery. The rectifier is given a 3-phase, 230 V supply. The current limiting resistance in series with the battery is of 8 Ω. Find the average value of battery charging current. Correct Answer 8.82 A

Vo = (3√2 x 230)/π = 310.56 V Draw the battery charging circuit, Vo = E + (Io x R) Io = (Vo – E)/R = (310.56 – 240)/8.

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 ?
