my score for junior research officer
15/17, 42/83
i-e 57/100.
just on the edge to clear academic atleast....

Junior Research Officer please share your results.

The question is correct and has a simple logic which has already been shared.

Dear Nadeem,
I have watched the logic but couldn't understand that. One more thing is that me and my friends have repeatedly sent emails regarding test pattern and injustice done to power engineers, so how can they say that no one has contacted them about test? They are telling lie, they just want to hide their incompetency regarding test.
Thanks

what is passing %age for both g.k & tech.........plz shre

Ok let me please.As we know that conductor passes through successive NS poles and produces 2 amplitudes of opposite polarity,So if there are 8 poles it means that 8 crust/troughs will be produced,as 1 crust+1 trough=1 wave so there will be 4 waves produced in 1 revolution which implies that the frequency will be 4Hz.

40%/7 marks for G.K portion
50%/42 marks for Technical portion

I am not sure about exact choices, but that will do great for anybody who want to take an idea of paper,
Now this is my request to everybody here, that please take some time after attempting test and jot down as many questions as you can, yes that's not allowed but I believe that's the only way we can help others

O my God!
You are not getting my point.
The wrong thing in the question is the unit Hz, if we replace Hz with cycles then the question becomes correct.

Now I am sure you both will agree to my point.

I inquired about wrong question only and NTS representative told me about the same.
I did not inquire about paper pattern.

Yom e Arfat is executed on 9th of zul haj.

The additional questions,as far as i remember:
Q1=The number of loads connected to the gate circuits are called?
Q2=A question about computer organization and programmer?
Q3=In a transformer the primary and seconday voltage has a phase difference of?
Q4=To transfer maximum,which property is used? (Impedance matching property)
Q5= The main goal of Power electronics is to?
Q6=Calculate the voltage of 50W toaster if the 12.5 amperes current passes through it for 5 seconds?

The question about only visible thing from moon was wrong alongside few-others.
