A) 2.7
B) 3.3
C) 2.3
D) 3.7
Correct Answer: B
Solution :
\[{{E}_{eq}}=\frac{\frac{{{E}_{1}}}{2{{R}_{1}}}+\frac{{{E}_{2}}}{{{R}_{2}}}+\frac{{{E}_{3}}}{2{{R}_{1}}}}{\frac{1}{2{{R}_{1}}}+\frac{1}{{{R}_{2}}}+\frac{1}{2{{R}_{1}}}}\]\[=\frac{\frac{2}{2}+\frac{4}{2}+\frac{4}{2}}{\frac{1}{2}+\frac{1}{2}+\frac{1}{2}}\] \[=\frac{5}{\frac{3}{2}}=\frac{10}{3}=3.3\]You need to login to perform this action.
