A generator is constructed by rotating a coil of N turns in a magnetic field B at a frequency f. The internal resistance of the coil is R and the cross sectional area of the coil is A. Choose the correct response for each of the following statements. True or False The average induced EMF doubles if the area A is doubled. The average induced EMF doubles if the resistance R is doubled. The average induced EMF doubles if the frequency f is doubled. The average induced EMF doubles if the magnetic field B is doubled. The maximum induced EMF occurs when the coil is rotated about the axis of t

4 is true
shamim
  • shamim
axis of t means
shamim
  • shamim
5 is not clear to me
shamim
  • shamim
but 5 may b true
shamim
  • shamim
i guessed

The maximum induced EMF occurs when the coil is rotated about the axis of the coil.
shamim
  • shamim
ya 5 is true
anonymous
  • anonymous
thats 5
shamim
  • shamim
now i wanna talk abt question 2
anonymous
  • anonymous
what about this The maximum induced EMF occurs when the coil is rotated about an axis parallel to the magnetic field lines.
shamim
  • shamim
ya its right
shamim
  • shamim
i know the curent creats for the rate of change of magnetic field. if the rate of change of magnetic field is higher then induced current will b higher
shamim
  • shamim
coil shoul cover magnetic field lines to create induced current
shamim
  • shamim
i think if the coil rotate along its axis then those magnetic field lines will go through the coil
shamim
  • shamim
and the rate of change of magnetic field will b higher
shamim
  • shamim
m i right
shamim
  • shamim
anyway i think ur question 2 is false
shamim
  • shamim
induced EMF does not depend on the resitance
shamim
  • shamim
of coil

i dont know much about this topic,i tried false and it didnt work,which means some other answer might be wrong
shamim
  • shamim
r u telling abt ur answer 2
anonymous
  • anonymous
yes
shamim
  • shamim
so u r telling ur answer 2 is right
shamim
  • shamim
then i wanna try it later
anonymous
  • anonymous
i havent tried true
shamim
  • shamim
i c
anonymous
  • anonymous
so u saying all of them is true,except 2?
shamim
  • shamim
ya
anonymous
  • anonymous
IS SAYING WRONG ANSWER

do u hv right answer
anonymous
  • anonymous
NOPE
shamim

sorry
anonymous
  • anonymous
no problem
shamim
  • shamim
then try 2,3,5 false
