A) \[60\,\,\Omega \]
B) \[6.67\,\,\Omega \]
C) \[66.67\,\,\Omega \]
D) \[50\,\,\Omega \]
Correct Answer: C
Solution :
\[\frac{1}{{{R}_{mix}}}\,\,=\,\,\frac{1}{2}\,\,\left( \frac{1}{{{R}_{1}}}+\frac{1}{{{R}_{2}}} \right)\] \[\frac{1}{{{R}_{mix}}}\,\,=\,\,\frac{1}{2}\,\,\left( \frac{1}{50}+\frac{1}{100} \right)\] \[{{R}_{mix}}=\,\,66.67\]You need to login to perform this action.
