Find the effective resistance between points A and B in ohms.
A) \[32\,\Omega \]
B) \[50\,\Omega \]
C) \[64\,\Omega \]
D) \[200\,\,\Omega \]
Correct Answer: A
Solution :
Let the effective resistance between points A and B be R \[{{\text{R}}_{1}}\text{=4}0\Omega ,{{R}_{2}}=\text{1}00+\text{6}0=\text{16}0\Omega \] \[\frac{1}{R}=\frac{1}{40}+\frac{1}{160}=\frac{4+1}{160}=\frac{5}{160}\], \[R=\frac{160}{5}=32\Omega \]
