Best answer by B.E students during viva...............





This is best answers by B.E students during viva. >---------------------> This one is for those who had nightmares during their Engineering Viva's (EEEs and ECEs). 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!"

Examiner: Do you know Ohm's Law???
Student: Sure Sir...
Examiner: Well...Narrate me...
Student: Which one Sir?? 1st or 2nd Law???
Examiner (getting shocked): How many Ohm's Law do you know???
Student (with confidence): Well sir...there are two Ohm's Laws…Every one knows...
Examiner (Smiling): Ok. Then tell me the 2nd one.
Student (thinking and thinking): Sir…I can't remember the entire law exactly...But the last portion of the law I can remember.
Examiner: Ok. You tell me the last portion only.
Student: Well sir. The last portion of the law tells like "This is called Ohm's Law
