................................................... Interviewer: Why is a thicker conductor necessary to carry a current in A.C.as compared to D.C. ? Candidate: An AC current goes up and down (drawing a sinusoid) and requires more space inside the wire, so the wire has to be thicker. Interviewer: How will you tell if that wall outlet carries AC or DC? Candidate: I will put my finger in. If it is pushed away, it is AC. If it gets stuck, it was DC. Interviewer: How will you reverse direction of an Induction motor? Candidate: I will remove the four bolts at the base, turn the motor around, and put back the bolts. Interviewer: How do you start a synchronous motor? Candidate: Vrrrrrrrmmmmmmmmmmmmmmmmmmm (in rising pitch) Interviewer: Stop! Stop! Candidate: rrrrrrrmmmmmmmmmmmmmmmmmmmm (in falling pitch) Interviewer: How do you limit surge current within an integrated circuit? Candidate: By using a miniature circuit breaker. External (to student) : "Why does a capacitor block DC but allow AC To pass through ? Student: See, a capacitor is like this ---| |--- , OK. DC comes straight, like this ----------, and the capacitor stops it. But AC,goes UP, DOWN, UP DOWN and jumps right over the capacitor!" Examiner: "What is a step-up transformer?" Student: "A transformer that is put on top of electric poles." Examiner (smiling): "And then what is a step-down transformer?" Student (hesitantly):"Uh - A transformer that is put in the basement or in a pit?" Examiner (pouncing): "Then what do you call a transformer that is installed on the ground?" (Student knows he is caught-can't answer) Examiner (impatiently): "Well?" Student (triumphantly): "A stepless transformer, sir!" TOP FACTS ABOUT ENGINEERS Engineers at work: Assignments solved by one and then carry out mass transfer operations throughout the class The most important machine for Engineers: Xerox Machine (Without which assignment Completion wouldn't be possible) Engineers Anthem: Hum hoge all clear Ek din, Mann me hai vishwas, pura hai vishwas, hum hoge all clear ek din Top two Engineering Rumours: Did you hear the results are being put up today at 5:30pm'?? Did you hear the exams are postponed by two weeks??? The most dreaded acronym for Engineers: ATKT ( After Trying Keep Trying) Common Engineering Dialogues after a paper: 'What is this pal, 60% of the paper was out of the syllabus' 'This was the worst paper set in the entire engineering history' 'I am failing'
