What is the resistance of the diode circuit between A and B. (`D_1` and `D_2` are ideal diodes)

A

7 `Omega`

B

8 `Omega`

C

9 `Omega`

D

10 `Omega`

Text Solution

Verified by Experts

The correct Answer is:
D
No current flows through `D_2`.
`therefore` Resistance (R') between A and C is given by `1/4+1/12=1/3=1/(R')`
`therefore` R'=3
`therefore ` Total resistance between A and B = 3 + 7 = `10Omega`
