A) 6
B) 4
C) 2
D) 8
Correct Answer: C
Solution :
As \[e=\frac{\Delta \phi }{\Delta t}\]or\[Ri=\frac{\Delta \phi }{\Delta t}\left( \because e=Ri \right)\] \[\Rightarrow \]\[\Delta \phi =R(i.\Delta t)\] \[=R\times \]area under i-t graph \[=10\times \frac{1}{2}\times 4\times 0.1=2\]we berYou need to login to perform this action.
