Hi

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.
---------------------------------------------------------------------
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!"
