The equivalent resistance between the points A and B, if `V_A gt V_B` is

A

`10 Omega`

B

`20 Omega`

C

`30 Omega`

D

`15 Omega`

Text Solution

Verified by Experts

The correct Answer is:
A
When `V_A gt V_B` the diode is forward biased and offers no resistance .
`therefore R=(20xx20)/(20+20)=10 Omega`
