INTERVIEW

Sub: electrical Engineering

People come up with peculiar or funny answers in interviews or exams:

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 DC. If it gets stuck, it
was AC.

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 transfomer 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!"

requires more space inside the wire,
funny in class

Examiner : "tell me the difference between a choke and a coil"

New graduate EE (think he know): "A choke in a circuit is to slow down the flow of electrons. On the othe hand, the coil is to shoot the electrons to go much faster, just like the spring !"

Examiner : "tell me the difference between a capacitor and an inductor"
New graduate EE (think for a moment): "In the earlier day they used to call a capacitor a straptor because it use to strap the electrons in to a small tank for later use. The inductor is a self generator, it can product enegy"

Examiner (smile on his face): "Our company design and develope electric car for future vehical. If we hire you, can you help us to design a new car that can go more than 100 mile/ gallon?"
New graduate EE (very happy and stand up to answer): "Sure I can, I already have in mind a principle of a new enegy free car. I will design a very big inductor. The driver just have to hold a big magnet and slide the magnet over the inductor, the free energy will product; the faster the magnet slide back and forth the faster the car can go. Virtually energy from the inductor is unlimited....(he goes on and on, and on)"...

Examiner (stand up and cry): "Ok..ok..ok I get the picture. I think you are very smart and I think you must work for a place very importance like NASA. I will call for NASA to instroduce you to them"

New graduate EE (confused, he think he may get a big job in NASA): "you mean NASA??....."

BATTLE OF TECHNOLOGIES

A Japanese, American, and Filipinos are curious about the technologies of their ancestors in communication. So what they do is dig a hole in their land. The dimension is 40 meter deep and a diameter of 5 meters.

Japanese was the first one to dig.

Japanese: We found a lot of copper! The technology of our ancestors is "Wire communications"

Next are the Americans.

Americans: We found a lot of fibers! So our ancestors use "Fiber optics communications"

Next are the Filipinos.

Filipinos: We found nothing!

The Americans and Japanese laughs.

Filipinos: Wait! can we dig 40 meters more?

Americans: OK you can dig 40 meters more! I hope you found something! ( They say it with laugh).

The Filipinos are hoping the find something after they dig 40 meters. After they dig 40 meters more, again they did not find anything.

The americans and japanese laugh again!

Filipinos: What are you laughing?

The americans and japanese laugh

Filipinos: These means that our ancestors are using "Wireless Communications" !

Japanese: Woahh
Americans: Unbelievable!
