The equivalent resistance between A and ...

The equivalent resistance between `A` and `B` is
.

A

`36 Omega` if `V_(A) gt V_(B)`

B

`18 Omega` if `V_(A) lt V_(B)`

C

Zero if `V_(A) lt V_(B)` and `54 Omega` if `V_(A) gt V_(B)`

D

Zero if `V_(A) gt V_(B)` and `54 Omega` If `V_(A) lt V_(B)`

Text Solution

Verified by Experts

The correct Answer is:
D
During `FB`, diode conducts and during `RB`, diode does not conduct.
