RPQ=(5/11)r,RQR=(4/11)r and RPR=(3/11)r ∴ RPQ is maximum.

Q. Six equal resistance are connected betweenpoints P, Q and R as shown in the figure. Thenthe net resistance will be maximum between :

P and Q

Q and R

P and Q

only two points

$R_{PQ} = \frac{5}{11} r, R_{QR} = \frac{4}{11} r$ and $R_{PR} = \frac{3}{11} r$ $∴$ $R_{PQ}$ is maximum.

RPQ​=115​r,RQR​=114​r and RPR​=113​r ∴ RPQ​ is maximum.

$R_{PQ} = \frac{5}{11} r, R_{QR} = \frac{4}{11} r$ and $R_{PR} = \frac{3}{11} r$ $∴$ $R_{PQ}$ is maximum.
