A) \[6\,\Omega \]
B) \[4\,\Omega \]
C) \[2.9\,\Omega \]
D) \[3.2\,\Omega \]
Correct Answer: C
Solution :
We know that, \[I=\frac{E-e}{R}\] According to the question, \[30=\left( \frac{e}{E} \right)\times 100\] \[30=\frac{e}{50}\times 100\] \[e=15\,V\] \[R=\frac{50-15}{12}=2.9\,\Omega \]You need to login to perform this action.
