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!"
