And those engg days..

I was going through some old mails, when I got reminded of this stupidly wonderful dialogue, reminding me of the ridiculous answers we used to give during our Engineering Viva.

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!
