A) 2 A
B) 1.5 A
C) 1A
D) 0.888 A
E) 0.75 A
Correct Answer: D
Solution :
The combined resistance of combination is \[R=R+\frac{r}{4}=2+\frac{1}{4}=\frac{9}{4}.\] \[V=2\,volt\] \[\therefore \] \[V=iR\] \[\Rightarrow \] \[i=\frac{V}{R}=\frac{2\times 4}{9}=\frac{8}{9}=0.888\,A\]You need to login to perform this action.
