Current Electricity 1 Question 15
15. Six equal resistances are connected between points $P, Q$ and $R$ as shown in the figure. Then, the net resistance will be maximum between
$(2004,2 M)$
(a) $P$ and $Q$
(b) $Q$ and $R$
(c) $P$ and $R$
(d) any two points
Show Answer
Solution:
- $R _{P Q}=\frac{5}{11} r, R _{Q R}=\frac{4}{11} r$ and $R _{P R}=\frac{3}{11} r$
$\therefore R _{P Q}$ is maximum.
Therefore, the correct option is (a).
