A) 6 Wb
B) 3 Wb
C) 4 Wb
D) 2 Wb
Correct Answer: B
Solution :
(b) 3 Wb The change in flux is given by, \[dq=\frac{d\phi }{dt}\] \[\Rightarrow d\phi =dq\times dt\] \[=(area\,\,of\,\,l-t\,\,graph)\times R\] \[=\left( \frac{1}{2}\times 0.2\times 6 \right)\times 5=0.6\times 5=3\,Wb\]You need to login to perform this action.
