The equivalent resistance of the circuit...

The equivalent resistance of the circuit shown in figure between the points A and B if `V_A lt V_B` is

A

`10 Omega`

B

`20 Omega`

C

`5 Omega`

D

`40 Omega`

Text Solution

Verified by Experts

The correct Answer is:
B
When `V_A lt V_B`, the diode is reverse biased and offers infinite resistance. No current flows through the upper branch
`therefore R=20 Omega`
