Group Title
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

shamim Group TitleBest ResponseYou've already chosen the best response.1
ya 5 is true
 one year ago

shamim Group TitleBest ResponseYou've already chosen the best response.1
now i wanna talk abt question 2
 one year ago

krypton Group TitleBest ResponseYou've already chosen the best response.0
what about this The maximum induced EMF occurs when the coil is rotated about an axis parallel to the magnetic field lines.

shamim Group TitleBest ResponseYou've already chosen the best response.1
ya its right

shamim Group TitleBest ResponseYou've already chosen the best response.1
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 Group TitleBest ResponseYou've already chosen the best response.1
coil shoul cover magnetic field lines to create induced current
 one year ago

shamim Group TitleBest ResponseYou've already chosen the best response.1
i think if the coil rotate along its axis then those magnetic field lines will go through the coil
 one year ago

shamim Group TitleBest ResponseYou've already chosen the best response.1
and the rate of change of magnetic field will b higher
 one year ago

shamim Group TitleBest ResponseYou've already chosen the best response.1
anyway i think ur question 2 is false
 one year ago

shamim Group TitleBest ResponseYou've already chosen the best response.1
induced EMF does not depend on the resitance

krypton Group TitleBest ResponseYou've already chosen the best response.0
i dont know much about this topic,i tried false and it didnt work,which means some other answer might be wrong
 one year ago

shamim Group TitleBest ResponseYou've already chosen the best response.1
r u telling abt ur answer 2
 one year ago

shamim Group TitleBest ResponseYou've already chosen the best response.1
so u r telling ur answer 2 is right
 one year ago

shamim Group TitleBest ResponseYou've already chosen the best response.1
then i wanna try it later
 one year ago

krypton Group TitleBest ResponseYou've already chosen the best response.0
i havent tried true
 one year ago

krypton Group TitleBest ResponseYou've already chosen the best response.0
so u saying all of them is true,except 2?
 one year ago

krypton Group TitleBest ResponseYou've already chosen the best response.0
IS SAYING WRONG ANSWER
 one year ago

shamim Group TitleBest ResponseYou've already chosen the best response.1
do u hv right answer
 one year ago

shamim Group TitleBest ResponseYou've already chosen the best response.1
ur answer 3 and 2 are false
 one year ago

krypton Group TitleBest ResponseYou've already chosen the best response.0
is still wrong
 one year ago

krypton Group TitleBest ResponseYou've already chosen the best response.0
no problem
 one year ago

shamim Group TitleBest ResponseYou've already chosen the best response.1
then try 2,3,5 false
 one year ago

krypton Group TitleBest ResponseYou've already chosen the best response.0
haha wrong :(
 one year ago

shamim Group TitleBest ResponseYou've already chosen the best response.1
if u know the right answer , let me know plz
 one year ago
