A) \[250\,Wb\]
B) \[275\,Wb\]
C) \[200\,Wb\]
D) \[225\,Wb\]
Correct Answer: A
Solution :
According to Faraday's law of electromagnetic induction, \[\varepsilon =\frac{d\phi }{dt}\] Also, \[\varepsilon =iR\] \[\therefore \,\,iR=\frac{d\phi }{dt}\Rightarrow \int{d\phi =R\int{idt}}\] Magnitude of change in flux \[(d\phi )=R\times \] area under current vs time graph or, \[d\phi =100\times \frac{1}{2}\times \frac{1}{2}\times 10=250Wb\]You need to login to perform this action.
