Gently lick me out, folks..

(This post is a bit technical as it involves an actual scene in an electronics lab in Engineering college. I am sorry, but I cannot translate the technicalities)

Location: Outside circuits lab, Govt Engineering College, Thrissur (Kerala)

Situation: S3 Electronics lab univ. exam

Smitha: Sunder… you look so happy.. are you not tense?

Sunder: No way! I have learnt all the experiments!!

Smitha and others: (wow, this guy’s so cool… and I am sweating…)

..

Smitha: We will step into the lab with right foot first. That way, we will have more luck.

Sunder: No way! I am a communist.. I don’t believe in superstitions.

Smitha: But Sunder, how confident are you on the experiments?

Sunder: I have studied all the experiments except UJT. UJT has not been asked for any of the batches who completed the lab exam till now (including A batch). So they will not ask today also. To prove my point, I will step into the lab with left foot.

Sunder steps into lab with left foot. Others with right foot. They look at invigilators – Sukumaran sir and Indira madam.

Sunder takes the sheet and slowly opens it… the experiment is.. UJT??!

Now comedy starts. Don’t know circuit diagram.

Sunder: Sir, I don’t know this experiment. Can you change this for me?

Sukumaran sir: Have you done this during class?

Sunder (almost whisper): yes… sir..

Sukumaran sir: Then it cannot be changed. Go and draw the circuit diagram!

Sunder goes back to seat… somehow draws a circuit diagram (how he drew, I will not explain). Takes it to invigilators.

Sukumaran sir: What is this?! Is this your circuit diagram?

Sunder: yes.. .sir…?

Sukumaran sir: This is wrong! Anyway, I will take your viva now. hFE of an npn transistor is 150. B-E cutoff voltage is set to 0.6v. E-C voltage is set to such-and-such and it is working in common emitter configuration. What is the base current in the transistor?

Sunder completely worried now. He looks at the calculator in his hand. Not very sure where to start.

After 3 min…

Sunder: Got it! Sir, it is 35A!

Sukumaran sir looks at him disbelievingly… “my dear, there is no such transistor in this world which can accept that base current…?”

(ok, for those who did not get the joke, the base current in a transistor never exceeds a few milliAmps)
[As though that explanation was enough]

PS: Sunder continues to be a communist, but from that day always steps for a new venture with right leg only.

Pinne communist karku left leg, right leg ennonnum illa...2um oru pole thanneya...

Communistinum kaalu maraam!

I thought communists jumps into situations (visheshenayulla plavam) to avoid the right left problem.

well ... i did my first practical today.and i will always enter a lab with my right leg first

And that is why u don't look at what others are doing or what happened before instead of doing what u r supposed to do!! Poor sunder.. Whatever happened to him???

Thanks for all comments!

Sunder lost the paper (11/100, the 11 contributed mostly out of his lab record)

But he entered the lab with right leg for the next supplimentary exam and passed.

I remembered of my electronics lab. After teaching MuP for 6 months our sir asked "how many pins are there for 8085?". The answers ranged from 8 - 64 !!

What a great web log. I spend hours on the net reading blogs, about tons of various subjects. I have to first of all give praise to whoever created your theme and second of all to you for writing what i can only describe as an fabulous article. I honestly believe there is a skill to writing articles that only very few posses and honestly you got it. The combining of demonstrative and upper-class content is by all odds super rare with the astronomic amount of blogs on the cyberspace.
