This one is for those who had nightmares during their Engineering Viva’s. They bring back fond memories for those who care to smile at the past..
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.
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!” .——————-good one 
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: H! ow will you reverse direction of an Induction motor?
Candidate: I will remove the four bolts at the x-ud, 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)
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 x-udment 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:
Assignme! nts 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 couldn’t be possible)
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
Common Engineering Dialogues after a paper:
‘What is this man, 60% o f the paper was out of the syllabus’
‘This was the worst paper set in the entire
engineering history’ ‘I am failing’
