hi all
any guesses?

 

[princesszahra]

phy
p31
first experiment is abt electricity
and second is about pendulum and stopwatch!

 

[henglin]

wow
thx alot.
what time are you taking it?

 

[sweeto]

wat do v hav to kno abt electricity????
simple circuits? diodes and variable resisters?potentiometers?.any guesses??

Hi!
how did u know wat is comin in practicalz.

 

[Syed.Mazahir.Rizvi]

in electrical there will be a diode immeresd in water or ice with attachd resistor...! in mechnical there will be a log hung wid retort stand vertically u have to attach a log to it horizontally...after doing so the displacement will occur...we have to find out the angle through which it displaced..hope this gna cme in exam...n it's a guess i guess

 

[sweeto]

thnx btw howcum we're able to do such ques relating diodes and ice and blah blah??.....isn't ther supposed to be a circuit or sumthing?

 

[Syed.Mazahir.Rizvi]

duh its obvious tht u will place every thing in circuit..its lyk attching a diode with a resistor in series then ammeter and powersupply in series and voltmeter in parallel and then immerse the diode and resistor in water/ice...!

can we electrocute da invigilator with dis crap....... :mrgreen: :mrgreen: :mrgreen: :mrgreen:

 

[Syed.Mazahir.Rizvi]

nope its only 3V D.C....i wish we could....this is one ov the most authentic guess right out ov a senior invigilators mouth from the confidentials...!

really?

u mean dis cn cum loooks rubbish to me

 

[Syed.Mazahir.Rizvi]

yup its rubbish but its possible to come if this aint leaked on large scale and British Council aint got any Plan B

 

[WellWIshER]

nah dude...dis is crap..
i mean wt will u measure..by dippin da flippin diode in water???


thts non-sense

 

[Syed.Mazahir.Rizvi]

u gna get reading by varing the voltage under water/ice and without it(smthin lyk it)...and then gna plot a graph!

 

[princesszahra]

hmm guesses abt practicals r quite accurate ppl!

 

[ashhadazam]

Immersing diode in water :O :O :O
Hope we dont get anything like this ...

 

[MAVtKnmJ]

Like princesszahra said, guesses for practicals are quite accurate And this diode dipped in water will definitely come!

Hello!!
it's okay with the experiment....i jst wanno knw the improvements n modification???? for eg: if its pendulumn n stopwatch, what shoud i write!!!!

@mazahir u said dat power supply would be 3V DC but a diode converts ac to dc.powersuply sd b ac??? dude do u know wat sort of calculations would be asked in da mechanical Q.
