An Engineering Story

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 x-ud, turn the motor around, and put back the

bolts.

Interviewer: How do y! ou start a synchronous mo! tor?
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 x-udment or in a pit?"
Examiner (pouncing): "Then what do you call a transformer that i! s 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

couldn'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'.
