One question of electrical i still remember no one ever could answer in first year viva was what is a three phase power
It went something like this
T: So dear x, you are smart guy..
X:
T: Turn on the fan speed, its hot, Garmi lag rhi hogi
X: (wah aaj Viva nikal gya maze se
thinking)
T: What is the phase of that power
X: err 1phase?
T: What if i connect 3 phase supply
X
Dunno
Sir its 1 phase, what can 3 phase do.
T
o i can't do that. But have you seen, outside this hall, our meter is 3 phase
X: (Arre am not an electrician
) Dunno sir
T: Why not make 5phases. Whats with 3 phases
X: Good question
T: Why do motors need 3 phases
X: Gyaan on even power
T: So i can make 100 phase supply for very even power output
X:
Won't make too much of a diffence i think after some stage
T: So you decided that 3 is enough and not more
X: ehh.. no, scientists must have
T: Who are these guys who decide whats good or not anyway. Americans think 3 is good enough, why can't it be 5. I like the number 5
X: (Deemag Kharaab hai Kya)
Yes Sir.
T: So we can same way decide that marks should be out of 60%
X: Ehh
T: Why not, who said it has to be 100% only. We can do what we like. 5 phase power, 60% marks.
X:
T: So you can go and we can safely assume that when you become an engineer you will make 5 phase power standard for india.
X:
That was a friend in electrical
We were laughing outside the hall.
