Six equal resistances are connected between points \(P, Q\) and \(R\) as shown in figure. Then net resistance will be maximum between
- A \(P\) and \(R\)
- B \(P\) and \(Q\)
- C \(Q\) and \(R\)
- D Any two points
Answer & Solution
Correct Answer
(B) \(P\) and \(Q\)
Step-by-step Solution
Detailed explanation
Resistance between \(\mathrm{P\,and} \,\mathrm{Q}\) \(r_{P Q}=r_{11}\left(\frac{r}{3}+\frac{r}{2}\right)=\frac{r \times \frac{5}{6} r}{r+\frac{5}{6} r}=\frac{5}{11} r\) Resistance between \(Q\) and \(R\)…
