A) \[7\text{ }\Omega \text{, }7\text{ }V\]
B) \[8\text{ }\Omega ,\,8\text{ }V\]
C) \[9\text{ }\Omega ,\text{ }9\text{ }V\]
D) \[9\text{ }\Omega ,10\text{ }V\]
Correct Answer: C
Solution :
(c) \[9\text{ }\Omega ,\text{ }9\text{ }V\] Here, \[\varepsilon =12\text{ }V,r=3\,\Omega ,\,l=1A,\,V=lR=\varepsilon -lr\] \[\therefore R=\frac{\varepsilon -lr}{l}=\frac{12-1\times 3}{1}\] \[=12-3=9\,\Omega \] And \[V=iR=1\times 9=9V\]You need to login to perform this action.
