The effective resistance between points ...

The effective resistance between points P and Q of the electrical circuit shown in the figure is :

A

`(2Rr)/(R+r)`

B

`(8(R+r))/(3R+r)`

C

`2r+4R`

D

`(5R)/(2)+2r`

Verified by Experts

The correct Answer is:

A

The circuit can be reduced to the one given alongside
`R_(e)=(2rR)/(r+R)`Hence, (A) is correct
