Humor at Exams

At viva voce:

External : How does the capacitor block DC but allow AC current 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!

External : How do you limit surge current within an integrated circuit?

Student  : By using a miniature circuit breaker

External : Why is a thicker conductor necessary to carry a current in A.C. as compared to D.C?

Student : An AC current goes up and down (drawing a sinusoidal) and requires more space inside the wire, so the wire has to be thicker.

Some of the freshmen students are so clueless, that they think General calculus  was a famous war hero!

The guy gets on a bus and starts threatening everybody: “I’ll integrate you! I’ll differentiate you!!!” So everybody gets scared and runs away. Only one person stays. The guy comes up to him and says: “Aren’t you scared, I’ll integrate you, I’ll differentiate you!!!” And the other guy says; “No, I am not scared, I am e^x.
