A) 2
B) 4
C) 6
D) None of these
Correct Answer: A
Solution :
\[\left| dq \right|=\frac{d\phi }{R}=idt=Area\,\,under\,\,i-t\,\,graph\] \[\therefore \,\,\,\,\,\,d\phi \,\,=\left( Area under\,\,i -t\,\,graph \right)R\] \[=\frac{1}{2}\times 4\times 0.1\times (10)=2\,Wb\]You need to login to perform this action.
