Four wires

AB,\,\,BC,\,\,CD,\,\,DA

of resistance

4\,\,ohm

each and a fifth wire

BD

of resistance

8\,\,ohm

are joined to form a rectangle

A\,B\,C\,D

of which

BD

is a diagonal. The effective resistance between the points

A

and

B

is

View answer and explanation

Correct option: D

\frac{8}{3}\,\,ohm

Option D (

\frac{8}{3}\,\,ohm

) is correct because the effective resistance is calculated by simplifying the circuit using series and parallel combinations.
