How was physics p52

can somebody come on chat?? i wanna discuss one query

 

[MLSW1994]

me too! I wanna ask about question 1...

 

[minie23]

Diagram for question 1 :

Diagram for question 1 :

Aoa! are you sure this the correct diagram??
I too made the same, except that i connected the CRO with AC supply n I didnt add the variable resistor...

I guess it must be good !
Have a look on w10 p51 ! The question is quite similar !

 

[N.M]

What was ur gradient n uncertainity??

 

[minie23]

My gradient was 4500 with powers of -6 or -7 ! :s can't remember ! =/

Btw, the independent variable was current, I and dependent variable was frequency, f !

 

[kalpaveen]

i was just wondering if i got the diagram wrong, does that mean my whole experiment is wrong???

I guess the independent was frequency and the dependent was current. The question clearly mentions it.

exactly!!!!!!!!

:O

what was kept constant ?
and what about the diagram ?

 

[magnesium]

:O

what was kept constant ?
and what about the diagram ?

no.of turns of the coil

 

[elbeyon]

and what about the diagram ?

I kept the no. of turns in the coil and the current from the power supply constant and used a variable frequency generator to vary the frequency.

How can you kept the current constant ? :O

 

[Silent Hunter]

didnt we have to use type of signal generator ?

 

[elbeyon]

How can you kept the current constant ? :O

Its simple. Use a rheostat and an ammeter. That's all !

 

[elbeyon]

didnt we have to use type of signal generator ?

why signal generator ? There was no reason for its use, I suppose.

 

[magnesium]

didnt we have to use type of signal generator ?

nooo that is used with loudspeaker

You said you considered the current as dependent which means "measure" with varying freq.
You can't keep it constant then !
