A) 3 \[\Omega \]
B) 6\[\Omega \]
C) 1.5 \[\Omega \]
D) 4 \[\Omega \]
Correct Answer: A
Solution :
\[E=40\,V,\]\[V=30\,V,\]\[r=a\,\Omega \] Internal resistance \[r=\left( \frac{E}{V}-1 \right)R=\left( \frac{40}{30}-1 \right)9\] \[=\frac{1}{3}\times 9=3\,\Omega \]You need to login to perform this action.
