### Engineering Classiccc....... Good one...... must read...

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

This is best answer 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 pastÃ¢â'¬Â¦

************************************************************************************
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!"

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)

************************************************************************************

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'

What is B.E?

8 semesters

80GB syllabus

80MB we study

80KB we remember

BINARY marks we get,

The Degree finally we get is BE

That is Brain Empty (B.E)
