Thirteen resistances each of resistance ...


Thirteen resistances each of resistance R ohm are connected in the circuit as shown in the figure above. The effective resistance between A and B is

A

`(4R)/(3)Omega`

B

`2R" "Omega`

C

`ROmega`

D

`(2R)/(3)Omega`

Text Solution

Verified by Experts

The correct Answer is:
D

It is a balanced wheatstone.s bridge circuit, so resistance R between CD is ineffective.
Resistance of `AEC=(2R.R)/(2R+R)=(2R)/(3)` etc.

`impliesR_(AB)=(2R)/(3)Omega`
