p52 phy

[ahmed t]

how was ur qp
i found it normal, although a lot of predictions where about the hall probe and hard things

It was easy, both questions!!!, question 1 was a simple experiment! there wasn't much to talk about, simple procedure

P 52 was easier than I predicted. Had practically freaked out before giving the exam. Definitely easier than some of the previous ques. papers.

i actualy found it annoying, the first quest is 15 marks but its such a simple experiment, not much to write about.

Exactly, it's simple really there wasn't much to talk about

what was the purpose of the hall probe??? why should we use it?????

hey guys, how did u measure the frequency of the current?????

 

[Kz99]

hey guys, how did u measure the frequency of the current?????

a device called frequency counter,

 

[loly23]

frequency counter??what's that??

 

[Kz99]

its just like a voltmeter....but instead it measure the frequency of AC voltage/current.

 

[loly23]

Oh!! i used a CRO. do you think it is good???

hey.....use an oscillloscope to measure frequency!!!!!The current is varied using a variable resistor!!!!

me too!!

 

[colloquial]

overall, how do u find the paper??? how many marks do u expect to earn on 30 ???

 

[Cyan]

The current should remain constant!

 

[colloquial]

but how the frequency could be changed then????
