The equivalent resistance between \(A\) and \(B\) is \(......\)
- A \(\frac{2}{3} \Omega\)
- B \(\frac{1}{2} \Omega\)
- C \(\frac{3}{2} \Omega\)
- D \(\frac{1}{3} \Omega\)
Answer & Solution
Correct Answer
(A) \(\frac{2}{3} \Omega\)
Step-by-step Solution
Detailed explanation
\(\frac{1}{ R _{ eq }}=\frac{1}{2}+\frac{1}{12}+\frac{1}{4}+\frac{1}{6}+\frac{1}{2}\) \(=\frac{6+1+3+2+6}{12}=\frac{18}{12}=\frac{3}{2}\) \(\Rightarrow \quad R_{ eq }=\frac{2}{3}\,\Omega\)
