In the circuit shown in fig. some potential difference is applied between A and B. The equivalent resistance between A and B is R.

A

No current flows through the `5 Omega` resistor.

B

`R = 15 Omega`

C

`R = 12.5 Omega`

D

`R = (18)/(5)Omega`

Text Solution

Verified by Experts

The correct Answer is:
A, D
,
Rearrangement of the circuit as shwon in fig. gives a balanced wheatstone bridge, and no current flows through the
`5Omega` resistor. It can thus be removed from the circuit.
