A) \[\frac{8}{3}A\]
B) \[\frac{9}{13}A\]
C) \[\frac{4}{13}A\]
D) \[\frac{1}{3}A\]
E) \[\frac{2}{3}A\]
Correct Answer: D
Solution :
\[\frac{1}{R}=\frac{1}{2}+\frac{1}{2}=1\] \[R=1\,\Omega \] Total resistance\[=R+5=1+5=6\,\Omega \] \[{{E}_{eff}}=\frac{{{E}_{1}}{{r}_{1}}+{{E}_{2}}{{r}_{2}}}{{{r}_{1}}+{{r}_{2}}}=\frac{2\times 2+2\times 2}{2+2}\] \[=2\,V\] \[i=\frac{{{E}_{ff}}}{R}=\frac{2}{6}=\frac{1}{3}A\]You need to login to perform this action.
